fgetgrent − get group file entry
#include
<grp.h>
#include <stdio.h>
#include <sys/types.h>
struct group *fgetgrent(FILE *stream);
The fgetgrent() function returns a pointer to a structure containing the group information from the file stream. The first time it is called it returns the first entry; thereafter, it returns successive entries. The file stream must have the same format as /etc/group.
The group structure is defined in <grp.h> 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 fgetgrent() function returns the group information structure, or NULL if there are no more entries or an error occurs.
