NAME
       getpw - Re-construct password line entry

SYNOPSIS
       #include <pwd.h>
       #include <sys/types.h>

       int getpw(uid_t uid, char *buf);

DESCRIPTION
       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 */
              };

RETURN VALUE
       The getpw() function returns 0 on success, or -1 if an error occurs.

ERRORS
       ENOMEM Insufficient memory to allocate passwd structure.

FILES

BUGS
       The  getpw()  function  is  dangerous  as  it may overflow the provided
       buffer buf.  It is obsoleted by getpwuid().
