getpw - Re-construct password line entry
Návod, kniha: Linux Programmer's Manual
#include <sys/types.h>
#include <pwd.h>
int getpw(uid_t uid, char *buf);
The
getpw() function re-constructs the password line entry for the given
user uid
uid in the buffer
buf. The returned buffer contains a
line of format
name:passwd:uid:gid:gecos:dir:shell
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 */
};
The
getpw() function returns 0 on success, or -1 if an error occurs.
- ENOMEM
- Insufficient memory to allocate passwd structure.
- /etc/passwd
- password database file
SYSVr2.
The
getpw() function is dangerous as it may overflow the provided buffer
buf. It is obsoleted by
getpwuid().
