fgetgrent - get group file entry
Návod, kniha: Linux Programmer's Manual
#include <stdio.h>
#include <sys/types.h>
#include <grp.h>
struct group *fgetgrent(FILE *stream);
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 */
};
The
fgetgrent() function returns the group information structure, or NULL
if there are no more entries or an error occurs.
- ENOMEM
- Insufficient memory to allocate group information
structure.
