    Command:

    fgetgrent

    
    
    

    SYNOPSIS

           #include <stdio.h>
           #include <sys/types.h>
           #include <grp.h>
    
           struct group *fgetgrent(FILE *stream);
    
       Feature Test Macro Requirements for glibc (see feature_test_macros(7)):
    
           fgetgrent(): _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 <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.
    
    
    

    CONFORMING TO
