.TH "COMEDI_GET_VERSION_CODE" "3" "02 October 2004" "" ""
.SH NAME
comedi_get_version_code \- Comedi version code
.SH SYNOPSIS
.sp
\fB#include <comedilib.h>
.sp
int comedi_get_version_code (comedi_t * \fIdevice\fB);
\fR
.SH "DESCRIPTION"
.PP
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.
.PP
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.
.PP
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.
