30 | =head1 DESCRIPTION | ||||
31 | |||||
32 | C<IO::Handle> is the base class for all other IO handle classes. It is | ||||
33 | not intended that objects of C<IO::Handle> would be created directly, | ||||
34 | but instead C<IO::Handle> is inherited from by several other classes | ||||
35 | in the IO hierarchy. | ||||
36 | |||||
37 | If you are reading this documentation, looking for a replacement for | ||||
38 | the C<FileHandle> package, then I suggest you read the documentation | ||||
39 | for C<IO::File> too. | ||||
40 | |||||
41 | =head1 CONSTRUCTOR | ||||
42 | |||||
43 | =over 4 | ||||
44 | |||||
45 | =item new () | ||||
46 | |||||
47 | Creates a new C<IO::Handle> object. | ||||
48 | |||||
49 | =item new_from_fd ( FD, MODE ) | ||||
50 | |||||
51 | Creates an C<IO::Handle> like C<new> does. | ||||
52 | It requires two parameters, which are passed to the method C<fdopen>; | ||||
53 | if the fdopen fails, the object is destroyed. Otherwise, it is returned | ||||
54 | to the caller. | ||||
55 | |||||
56 | =back | ||||
57 | |||||
58 | =head1 METHODS | ||||
59 | |||||
60 | See L<perlfunc> for complete descriptions of each of the following | ||||
61 | supported C<IO::Handle> methods, which are just front ends for the | ||||
62 | corresponding built-in functions: | ||||
63 | |||||
64 | $io->close | ||||
65 | $io->eof | ||||
66 | $io->fcntl( FUNCTION, SCALAR ) | ||||
67 | $io->fileno | ||||
68 | $io->format_write( [FORMAT_NAME] ) | ||||
69 | $io->getc | ||||
70 | $io->ioctl( FUNCTION, SCALAR ) | ||||
71 | $io->read ( BUF, LEN, [OFFSET] ) | ||||
72 | $io->print ( ARGS ) | ||||
73 | $io->printf ( FMT, [ARGS] ) | ||||
74 | $io->say ( ARGS ) | ||||
75 | $io->stat | ||||
76 | $io->sysread ( BUF, LEN, [OFFSET] ) | ||||
77 | $io->syswrite ( BUF, [LEN, [OFFSET]] ) | ||||
78 | $io->truncate ( LEN ) | ||||
79 | |||||
80 | See L<perlvar> for complete descriptions of each of the following | ||||
81 | supported C<IO::Handle> methods. All of them return the previous | ||||
82 | value of the attribute and takes an optional single argument that when | ||||
83 | given will set the value. If no argument is given the previous value | ||||
84 | is unchanged (except for $io->autoflush will actually turn ON | ||||
85 | autoflush by default). | ||||
86 | |||||
87 | $io->autoflush ( [BOOL] ) $| | ||||
88 | $io->format_page_number( [NUM] ) $% | ||||
89 | $io->format_lines_per_page( [NUM] ) $= | ||||
90 | $io->format_lines_left( [NUM] ) $- | ||||
91 | $io->format_name( [STR] ) $~ | ||||
92 | $io->format_top_name( [STR] ) $^ | ||||
93 | $io->input_line_number( [NUM]) $. | ||||
94 | |||||
95 | The following methods are not supported on a per-filehandle basis. | ||||
96 | |||||
97 | IO::Handle->format_line_break_characters( [STR] ) $: | ||||
98 | IO::Handle->format_formfeed( [STR]) $^L | ||||
99 | IO::Handle->output_field_separator( [STR] ) $, | ||||
100 | IO::Handle->output_record_separator( [STR] ) $\ | ||||
101 | |||||
102 | IO::Handle->input_record_separator( [STR] ) $/ | ||||
103 | |||||
104 | Furthermore, for doing normal I/O you might need these: | ||||
105 | |||||
106 | =over 4 | ||||
107 | |||||
108 | =item $io->fdopen ( FD, MODE ) | ||||
109 | |||||
110 | C<fdopen> is like an ordinary C<open> except that its first parameter | ||||
111 | is not a filename but rather a file handle name, an IO::Handle object, | ||||
112 | or a file descriptor number. (For the documentation of the C<open> | ||||
113 | method, see L<IO::File>.) | ||||
114 | |||||
115 | =item $io->opened | ||||
116 | |||||
117 | Returns true if the object is currently a valid file descriptor, false | ||||
118 | otherwise. | ||||
119 | |||||
120 | =item $io->getline | ||||
121 | |||||
122 | This works like <$io> described in L<perlop/"I/O Operators"> | ||||
123 | except that it's more readable and can be safely called in a | ||||
124 | list context but still returns just one line. If used as the conditional | ||||
125 | within a C<while> or C-style C<for> loop, however, you will need to | ||||
126 | emulate the functionality of <$io> with C<< defined($_ = $io->getline) >>. | ||||
127 | |||||
128 | =item $io->getlines | ||||
129 | |||||
130 | This works like <$io> when called in a list context to read all | ||||
131 | the remaining lines in a file, except that it's more readable. | ||||
132 | It will also croak() if accidentally called in a scalar context. | ||||
133 | |||||
134 | =item $io->ungetc ( ORD ) | ||||
135 | |||||
136 | Pushes a character with the given ordinal value back onto the given | ||||
137 | handle's input stream. Only one character of pushback per handle is | ||||
138 | guaranteed. | ||||
139 | |||||
140 | =item $io->write ( BUF, LEN [, OFFSET ] ) | ||||
141 | |||||
142 | This C<write> is somewhat like C<write> found in C, in that it is the | ||||
143 | opposite of read. The wrapper for the perl C<write> function is | ||||
144 | called C<format_write>. However, whilst the C C<write> function returns | ||||
145 | the number of bytes written, this C<write> function simply returns true | ||||
146 | if successful (like C<print>). A more C-like C<write> is C<syswrite> | ||||
147 | (see above). | ||||
148 | |||||
149 | =item $io->error | ||||
150 | |||||
151 | Returns a true value if the given handle has experienced any errors | ||||
152 | since it was opened or since the last call to C<clearerr>, or if the | ||||
153 | handle is invalid. It only returns false for a valid handle with no | ||||
154 | outstanding errors. | ||||
155 | |||||
156 | =item $io->clearerr | ||||
157 | |||||
158 | Clear the given handle's error indicator. Returns -1 if the handle is | ||||
159 | invalid, 0 otherwise. | ||||
160 | |||||
161 | =item $io->sync | ||||
162 | |||||
163 | C<sync> synchronizes a file's in-memory state with that on the | ||||
164 | physical medium. C<sync> does not operate at the perlio api level, but | ||||
165 | operates on the file descriptor (similar to sysread, sysseek and | ||||
166 | systell). This means that any data held at the perlio api level will not | ||||
167 | be synchronized. To synchronize data that is buffered at the perlio api | ||||
168 | level you must use the flush method. C<sync> is not implemented on all | ||||
169 | platforms. Returns "0 but true" on success, C<undef> on error, C<undef> | ||||
170 | for an invalid handle. See L<fsync(3c)>. | ||||
171 | |||||
172 | =item $io->flush | ||||
173 | |||||
174 | C<flush> causes perl to flush any buffered data at the perlio api level. | ||||
175 | Any unread data in the buffer will be discarded, and any unwritten data | ||||
176 | will be written to the underlying file descriptor. Returns "0 but true" | ||||
177 | on success, C<undef> on error. | ||||
178 | |||||
179 | =item $io->printflush ( ARGS ) | ||||
180 | |||||
181 | Turns on autoflush, print ARGS and then restores the autoflush status of the | ||||
182 | C<IO::Handle> object. Returns the return value from print. | ||||
183 | |||||
184 | =item $io->blocking ( [ BOOL ] ) | ||||
185 | |||||
186 | If called with an argument C<blocking> will turn on non-blocking IO if | ||||
187 | C<BOOL> is false, and turn it off if C<BOOL> is true. | ||||
188 | |||||
189 | C<blocking> will return the value of the previous setting, or the | ||||
190 | current setting if C<BOOL> is not given. | ||||
191 | |||||
192 | If an error occurs C<blocking> will return undef and C<$!> will be set. | ||||
193 | |||||
194 | =item binmode( [LAYER] ) | ||||
195 | |||||
196 | C<binmode> sets C<binmode> on the underlying C<IO> object, as documented | ||||
197 | in C<perldoc -f binmode>. | ||||
198 | |||||
199 | C<binmode> accepts one optional parameter, which is the layer to be | ||||
200 | passed on to the C<binmode> call. | ||||
201 | |||||
202 | =back | ||||
203 | |||||
204 | |||||
205 | If the C functions setbuf() and/or setvbuf() are available, then | ||||
206 | C<IO::Handle::setbuf> and C<IO::Handle::setvbuf> set the buffering | ||||
207 | policy for an IO::Handle. The calling sequences for the Perl functions | ||||
208 | are the same as their C counterparts--including the constants C<_IOFBF>, | ||||
209 | C<_IOLBF>, and C<_IONBF> for setvbuf()--except that the buffer parameter | ||||
210 | specifies a scalar variable to use as a buffer. You should only | ||||
211 | change the buffer before any I/O, or immediately after calling flush. | ||||
212 | |||||
213 | WARNING: The IO::Handle::setvbuf() is not available by default on | ||||
214 | Perls 5.8.0 and later because setvbuf() is rather specific to using | ||||
215 | the stdio library, while Perl prefers the new perlio subsystem instead. | ||||
216 | |||||
217 | WARNING: A variable used as a buffer by C<setbuf> or C<setvbuf> B<must not | ||||
218 | be modified> in any way until the IO::Handle is closed or C<setbuf> or | ||||
219 | C<setvbuf> is called again, or memory corruption may result! Remember that | ||||
220 | the order of global destruction is undefined, so even if your buffer | ||||
221 | variable remains in scope until program termination, it may be undefined | ||||
222 | before the file IO::Handle is closed. Note that you need to import the | ||||
223 | constants C<_IOFBF>, C<_IOLBF>, and C<_IONBF> explicitly. Like C, setbuf | ||||
224 | returns nothing. setvbuf returns "0 but true", on success, C<undef> on | ||||
225 | failure. | ||||
226 | |||||
227 | Lastly, there is a special method for working under B<-T> and setuid/gid | ||||
228 | scripts: | ||||
229 | |||||
230 | =over 4 | ||||
231 | |||||
232 | =item $io->untaint | ||||
233 | |||||
234 | Marks the object as taint-clean, and as such data read from it will also | ||||
235 | be considered taint-clean. Note that this is a very trusting action to | ||||
236 | take, and appropriate consideration for the data source and potential | ||||
237 | vulnerability should be kept in mind. Returns 0 on success, -1 if setting | ||||
238 | the taint-clean flag failed. (eg invalid handle) | ||||
239 | |||||
240 | =back | ||||
241 | |||||
242 | =head1 NOTE | ||||
243 | |||||
244 | An C<IO::Handle> object is a reference to a symbol/GLOB reference (see | ||||
245 | the L<Symbol> package). Some modules that | ||||
246 | inherit from C<IO::Handle> may want to keep object related variables | ||||
247 | in the hash table part of the GLOB. In an attempt to prevent modules | ||||
248 | trampling on each other I propose the that any such module should prefix | ||||
249 | its variables with its own name separated by _'s. For example the IO::Socket | ||||
250 | module keeps a C<timeout> variable in 'io_socket_timeout'. | ||||

258 | =head1 BUGS | ||||
259 | |||||
260 | Due to backwards compatibility, all filehandles resemble objects | ||||
261 | of class C<IO::Handle>, or actually classes derived from that class. | ||||
262 | They actually aren't. Which means you can't derive your own | ||||
263 | class from C<IO::Handle> and inherit those methods. | ||||
