15 The putgrent() function is the counterpart for fgetgrent(3). The func‐
16 tion writes the content of the provided struct group into the file
17 pointed to by fp. The list of group members must be NULL terminated or
18 NULL initialized.
19
20 The struct group is defined as follows:
21
22 struct group {
23 char *gr_name; /* group name */
24 char *gr_passwd; /* group password */
25 gid_t gr_gid; /* group ID */
26 char **gr_mem; /* group members */
27 };
28
30 The function returns zero on success, and a non-zero value on error.
31
33 This function is a GNU extension.
