SYNOPSIS #include <stdio.h> #include <sys/types.h> #include <grp.h>

struct group { char *gr_name; /* group name */ char *gr_passwd; /* group password */ gid_t gr_gid; /* group ID */ char **gr_mem; /* group members */ };

RETURN VALUE The fgetgrent() function returns the group information structure, or NULL if there are no more entries or an error occurs.
