struct group *fgetgrent(FILE *stream);

Feature Test Macro Requirements for glibc (see feature_test_macros(7)):

fgetgrent():
Since glibc 2.19:
_DEFAULT_SOURCE
Glibc 2.19 and earlier:
_SVID_SOURCE

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 as follows:

struct group {
char *gr_name; /bin /boot /dead.letter /dev /etc /home /initrd /lib /lib64 /lost+found /media /mnt /opt /proc /release-notes.html /release-notes.txt /root /run /sbin /srv /sys /tmp /usr /var group name bodies/ usr/
char *gr_passwd; /bin /boot /dead.letter /dev /etc /home /initrd /lib /lib64 /lost+found /media /mnt /opt /proc /release-notes.html /release-notes.txt /root /run /sbin /srv /sys /tmp /usr /var group password bodies/ usr/
gid_t gr_gid; /bin /boot /dead.letter /dev /etc /home /initrd /lib /lib64 /lost+found /media /mnt /opt /proc /release-notes.html /release-notes.txt /root /run /sbin /srv /sys /tmp /usr /var group ID bodies/ usr/
char **gr_mem; /bin /boot /dead.letter /dev /etc /home /initrd /lib /lib64 /lost+found /media /mnt /opt /proc /release-notes.html /release-notes.txt /root /run /sbin /srv /sys /tmp /usr /var NULL-terminated array of pointers
to names of group members bodies/ usr/
};

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.
