putgrent − write a group database entry to a file
#define
_GNU_SOURCE
#include <grp.h>
int putgrent(const struct group *grp, FILE *fp);
The putgrent() function is the counterpart for fgetgrent(). 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 non-zero value on error.
This function is a GNU extension.
