PUTGRENT(3) Linux Programmer's Manual PUTGRENT(3)
putgrent - write a group database entry to a file
#define _GNU_SOURCE /* See feature_test_macros(7) */
#include <grp.h>
int putgrent(const struct group *grp, FILE *fp);
The putgrent() function is the counterpart for fgetgrent(3). The function
writes the content of the provided struct group into the file pointed to by
fp. 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.
This function is a GNU extension.
