fgetpwent − get password file entry
#include
<pwd.h> 
#include <stdio.h> 
#include <sys/types.h>
struct passwd *fgetpwent(FILE *stream);
The fgetpwent() function returns a pointer to a structure containing the broken out fields of a line in 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/passwd.
The passwd structure is defined in <pwd.h> as follows:
struct passwd {
| /* user name */  | |||
| /* user password */  | |||
| /* user id */  | |||
| /* group id */ | 
char *pw_gecos; /* real name */
| /* home directory */ | 
char *pw_shell; /* shell
program */ 
};
The fgetpwent() function returns the passwd structure, or NULL if there are no more entries or an error occurs.
| ENOMEM | Insufficient memory to allocate passwd structure. |
