NAME

       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

       ENOMEM Insufficient memory to allocate group information structure.

SYNOPSIS

       #include <stdio.h>

   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

       SVr4.
