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

	      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.
