Function Documentation

int VMPI_Stream_read	(	VMPI_Stream *	st,
		char *	buff,
		unsigned int	block_count,
		VMPI_Stream_blocking	block
	)

Read data from a VMPI_Stream.

Parameters

st	target stream
buff	buffer to write to
block_count	number of blocks
block	should this call be a blocking one

Returns

the size of read data if positive, a VMPI_Return_Status otherwise
