Member Function Documentation

XnPlayerInputStreamInterface::void ( XN_CALLBACK_TYPE * Close )

Closes the stream.

Parameters:

pCookie [in] A cookie that was received with this interface.

XnPlayerInputStreamInterface::XnStatus ( XN_CALLBACK_TYPE * Open )

Opens the stream for reading.

Parameters:

pCookie [in] A cookie that was received with this interface.

XnPlayerInputStreamInterface::XnStatus ( XN_CALLBACK_TYPE * Read )

Reads data from the stream. May read less data than asked, if the stream is near its end. This is not considered an error.

Parameters:

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.

XnPlayerInputStreamInterface::XnStatus ( XN_CALLBACK_TYPE * Seek )

Sets the stream's pointer to the specified position.

Parameters:

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

XnPlayerInputStreamInterface::XnUInt32 ( XN_CALLBACK_TYPE * Tell )

Tells the current stream position

Parameters:

pCookie [in] A cookie that was received with this interface.
