comedi_get_version_code(3) 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.
