comedi_get_version_code — Comedi version code


#include <comedilib.h>

int comedi_get_version_code (comedi_t * device);


Returns the Comedi kernel module version code.  A valid Comedi device referenced by the parameter device is necessary to communicate with the kernel module.  On error, -1 is returned.

The version code is encoded as a bitfield of three 8-bit numbers.  For example, 0x00073d is the version code for version 0.7.61.

This function is of limited usefulness.  A typical mis-application of this function is to use it to determine if a certain feature is supported.  If the application needs to know of the existence of a particular feature, an existence test function should be written and put in the Comedilib source.
