format as /etc/group (see group(5)).
- 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 */ - };
RETURN VALUE
The fgetgrent() function returns a pointer to a group structure, or
NULL if there are no more entries or an error occurs.
ERRORS
ENOMEM Insufficient memory to allocate group structure.
