NAME
       fgetgrent - get group file entry

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

       struct group *fgetgrent(FILE *stream);

DESCRIPTION
       The fgetgrent() function returns a pointer to a structure containing the group information
       from the file stream.  The first time it is called it returns the first entry; thereafter,
       it returns successive entries.  The file stream must have the same format as /etc/group.

       The group structure is defined in <grp.h> as follows:

	      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.

ERRORS
       ENOMEM Insufficient memory to allocate group information structure.
