getpw — Re-construct password line entry
#define _GNU_SOURCE #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 ID
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;char * pw_passwd;uid_t pw_uid;gid_t pw_gid;char * pw_gecos;char * pw_dir;char * pw_shell;};
No user corresponding to uid.
Insufficient memory to allocate passwd structure.
The getpw() function is
dangerous as it may overflow the provided buffer buf. It is obsoleted by
getpwuid(3).
endpwent(3), fgetpwent(3), getpwent(3), getpwnam(3), getpwuid(3), putpwent(3), setpwent(3), passwd(5)
