GCmdT()

GReturn GCALL GCmdT	(	GCon	g,
		GCStringIn	command,
		GCStringOut	trimmed_response,
		GSize	response_len,
		GCStringOut *	front
	)

Wrapper around GCommand that trims the response.

For use when the return value is desired, is ASCII (not binary), and the response should be trimmed of trailing colon, whitespace, and optionally leading space.

Parameters

g	Connection's handle.
command	Null-terminated command string to send to the controller.
trimmed_response	The trimmed response from the controller. Trailing space is trimmed by null terminating any trailing spaces, carriage returns, or line feeds.
response_len	The length of the trimmed_response buffer.
front	If non-null, upon return *front will point to the first non-space character in trimmed_response. This allows trimming the front of the string without modifying the user's buffer pointer, which may be allocated on the heap.

Returns

The success status or error code of the function. See gclib_errors.h for possible values.

See x_gcommand.cpp for an example.
