DESCRIPTION
The fgetgrent() function returns a pointer to a structure containing
the group information from the file referred to by stream. The first
time it is called it returns the first entry; thereafter, it returns
successive entries. The file referred to by stream must have the same
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. In the event of
an error, errno is set to indicate the cause.
ERRORS
ENOMEM Insufficient memory to allocate group structure.
