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 the group information structure, or NULL if there are no more entries or an error occurs.  

ERRORS
