putgrent(3) Library Functions Manual putgrent(3)
putgrent - write a group database entry to a file
Standard C library (libc, -lc)
#define _GNU_SOURCE /* See feature_test_macros(7) */
#include <grp.h>
int putgrent(const struct group *restrict grp, FILE *restrict stream);
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 */
};
The function returns zero on success, and a nonzero value on
error.
For an explanation of the terms used in this section, see
attributes(7).
