fgetgrent - get group file entry


SYNOPSIS

       #include <grp.h>
       #include <stdio.h>
       #include <sys/types.h>

       struct group *fgetgrent(FILE *stream);


DESCRIPTION

       The  fgetgrent() function returns a pointer to a structure
       containing the group information  from  the  file  stream.
       The  first  time  it is called it returns the first entry;
       thereafter,  it  returns  successive  entries.   The  file
       stream must have the same format as /etc/group.

       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

              structure.
