GCommand()

GCLIB_DLL_EXPORTED GReturn GCALL GCommand	(	GCon	g,
		GCStringIn	command,
		GBufOut	buffer,
		GSize	buffer_len,
		GSize *	bytes_returned
	)

Performs a command-and-response transaction on the connection.

Parameters

g	Connection's handle.
command	Null-terminated command string to send to the controller. The library will append a carriage return to the command string.
buffer	Buffer for the response. Will be filled with the response from the controller. The data will be null terminated unless the function returns G_BAD_LOST_DATA due to the buffer being too small to hold the data.
buffer_len	The size of the response buffer.
bytes_returned	The size of the data returned from the controller. This does not include null termination. This argument may be null if the value is not desired.

Returns

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

See x_gcommand.cpp for an example.
