Public Member Functions inherited from gate_stream_t
gate_result_t	read (char *buffer, gate_size_t bufferlength, gate_size_t *returned)
	Read bytes from stream and stores them in the given buffer.
gate_result_t	peek (char *buffer, gate_size_t bufferlength, gate_size_t *returned)
	Tries to read bytes from the stream, but leaves them in its input buffer to be read again.
gate_result_t	write (char const *buffer, gate_size_t bufferlength, gate_size_t *written)
	Writes bytes from the given buffer into the stream.
gate_result_t	flush ()
	Instructs the stream to flush its internal buffers and make current status persistent.
Public Member Functions inherited from gate_object_t
char const *	get_interface_name ()
	Returns on object's interface path name.
void	release ()
	Decrease object's reference counter, releases the object when count reaches zero.
int	retain ()
	Increase object's reference counter.

Detailed Description

Member Function Documentation

read_err()

gate_result_t read_err	(	char *	buffer,
		gate_size_t	bufferlength,
		gate_size_t *	returned )

Reads data from ERR-output-stream generated in the processes.

Parameters

[in]	buffer	Pointer to buffer receiving ERR data content
[in]	bufferlength	Capacity of buffer in bytes
[out]	returned	Pointer to variable receiving the amount of bytes retrieved from ERR stream

Returns

GATE_RESULT_* result code
