boost::interprocess::xsi_key
// In header: <boost/interprocess/xsi_key.hpp> class xsi_key { public: // construct/copy/destruct (); (); (, ); // public member functions () ; };
A class that wraps XSI (System V) key_t type. This type calculates key_t from path and id using ftok, sets key to a specified value, or sets key to IPC_PRIVATE using the default constructor.
xsi_key
public
construct/copy/destruct();
Default constructor. Represents a private xsi_key
.
( key);Creates a new XSI key using a specified value. Constructor is explicit to avoid ambiguity with shmid.
