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
