SYNOPSIS
       #include <stdio.h>
       #include <sys/types.h>

DESCRIPTION
       The  fgetgrent()	 function returns a pointer to a structure containing

	      struct group {
		      char    *gr_name;	       /* group name */
		      char    *gr_passwd;      /* group password */
		      gid_t   gr_gid;	       /* group id */
		      char    **gr_mem;	       /* group members */
	      };

RETURN VALUE
       The fgetgrent() function returns the group information  structure,  or
       NULL if there are no more entries or an error occurs.
