struct group *fgetgrent(FILE *stream);
Feature Test Macro Requirements for glibc (see feature_test_macros(7)):
fgetgrent(): _SVID_SOURCE
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 */
};
The fgetgrent() function returns a pointer to a group structure, or NULL if there are no more entries or an error occurs.
