Návod, kniha: Linux Programmer's Manual

STRUČNĚ

#include <stdio.h>
#include <sys/types.h>
#include <pwd.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 {
        char    *pw_name;		/* user name */
        char    *pw_passwd;		/* user password */
        uid_t   pw_uid;			/* user id */
        gid_t   pw_gid;			/* group id */
        char    *pw_gecos;      	/* real name */
        char    *pw_dir;  		/* home directory */
        char    *pw_shell;      	/* shell program */
};
