NAME         top

       putgrent - write a group database entry to a file

SYNOPSIS         top

       #define _GNU_SOURCE         /* See feature_test_macros(7) */

DESCRIPTION         top

       The putgrent() function is the counterpart for fgetgrent(3).  The
       function writes the content of the provided struct group into the
       stream.  The list of group members must be NULL-terminated or NULL-
       initialized.
       The struct group is defined 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         top

       The function returns zero on success, and a nonzero value on error.
