XnUInt64(* | Tell64 )(void *pCookie) |
An interface used for communication between OpenNI and a player module. This interface is used by a player module to receive recorded data from OpenNI, which knows where to get them according to one of the values of XnRecordMedium.
void(* XnPlayerInputStreamInterface::Close) (void *pCookie) |
Closes the stream.
pCookie | [in] A cookie that was received with this interface. |
XnStatus(* XnPlayerInputStreamInterface::Open) (void *pCookie) |
Opens the stream for reading.
pCookie | [in] A cookie that was received with this interface. |
XnStatus(* XnPlayerInputStreamInterface::Read) (void *pCookie, void *pBuffer, XnUInt32 nSize, XnUInt32 *pnBytesRead) |
Reads data from the stream. May read less data than asked, if the stream is near its end. This is not considered an error.
pCookie | [in] A cookie that was received with this interface. |
pBuffer | [out] A pointer to the buffer to read into. |
nSize | [in] Number of bytes to read. |
pnBytesRead | [out] Optional. Number of bytes actually read. |
XnStatus(* XnPlayerInputStreamInterface::Seek) (void *pCookie, XnOSSeekType seekType, const XnInt32 nOffset) |
Sets the stream's pointer to the specified position.
pCookie | [in] A cookie that was received with this interface. |
seekType | [in] Specifies how to seek - according to current position, end or beginning. |
nOffset | [in] Specifies how many bytes to move |
XnStatus(* XnPlayerInputStreamInterface::Seek64) (void *pCookie, XnOSSeekType seekType, const XnInt64 nOffset) |
Sets the stream's pointer to the specified position. (64bit version, for large files)
pCookie | [in] A cookie that was received with this interface. |
seekType | [in] Specifies how to seek - according to current position, end or beginning. |
nOffset | [in] Specifies how many bytes to move |
XnUInt32(* XnPlayerInputStreamInterface::Tell) (void *pCookie) |
Tells the current stream position
pCookie | [in] A cookie that was received with this interface. |
XnUInt64(* XnPlayerInputStreamInterface::Tell64) (void *pCookie) |
Tells the current position in the stream. (64bit version, for large files)
pCookie | [in] A cookie that was received with this interface. |
pPos | [out] The position of the stream. |
