which head file for major and minor function?

Code:

#include <sys/types.h>
#include <sys/stat.h>
#include <sys/termios.h>
#include <stdio.h>
#include <stdlib.h>		
#include <stddef.h>		
#include <string.h>		
#include <unistd.h>		
#include <signal.h>	
#include <sys/mkdev.h>

int
main(int argc, char *argv[])
{
  int	i;
  struct stat	buf;

  for (i = 1; i < argc; i++) {
	printf("%s: ", argv[i]);
	if (stat(argv[i], &buf) < 0) {
		err_ret("stat error");
		continue;
	}

	printf("dev = %d/%d", major(buf.st_dev),  minor(buf.st_dev));

	if (S_ISCHR(buf.st_mode) || S_ISBLK(buf.st_mode)) {
		printf(" (%s) rdev = %d/%d",(S_ISCHR(buf.st_mode)) ? "character" : "block",
		major(buf.st_rdev), minor(buf.st_rdev));
	}
	printf("\n");
  }

  exit(0);
}

when I compile above code,it raise following error:
Undefined first referenced
symbol in file
major /var/tmp/ccwkRAdK.o
minor /var/tmp/ccwkRAdK.o
ld: fatal: Symbol referencing errors. No output written to a.out

What raise above error? which head file include major and minor function? How to correct my above code?

Thanks!

glxqueryversion

GLXQUERYVERSION(3G)						   OpenGL Manual					       GLXQUERYVERSION(3G)

NAME

       glXQueryVersion - return the version numbers of the GLX extension

C SPECIFICATION

       Bool glXQueryVersion(Display * dpy, int * major, int * minor);

PARAMETERS

       dpy
	   Specifies the connection to the X server.

       major
	   Returns the major version number of the GLX server extension.

       minor
	   Returns the minor version number of the GLX server extension.

DESCRIPTION

       glXQueryVersion returns the major and minor version numbers of the GLX extension implemented by the server associated with connection dpy.
       Implementations with the same major version number are upward compatible, meaning that the implementation with the higher minor number is a
       superset of the version with the lower minor number.

       major and minor do not return values if they are specified as NULL.

ERRORS

       glXQueryVersion returns False if it fails, True otherwise.

       major and minor are not updated when False is returned.
