PROLOG
       This  manual  page is part of the POSIX Programmer's Manual.  The Linux
       implementation of this interface may differ (consult the  corresponding
       Linux  manual page for details of Linux behavior), or the interface may
       not be implemented on Linux.
NAME
       pwd.h -- password structure
SYNOPSIS
       #include <pwd.h>
DESCRIPTION
       The <pwd.h> header shall define the  struct  passwd,  structure,  which
       shall include at least the following members:
           char    *pw_name   User's login name.
           uid_t    pw_uid    Numerical user ID.
           gid_t    pw_gid    Numerical group ID.
           char    *pw_dir    Initial working directory.
           char    *pw_shell  Program to use as shell.
       The  <pwd.h>  header shall define the gid_t, uid_t, and size_t types as
       described in <sys/types.h>.
       The following shall be declared as functions and may also be defined as
       macros. Function prototypes shall be provided.
           void           endpwent(void);
           struct passwd *getpwent(void);
           struct passwd *getpwnam(const char *);
           int            getpwnam_r(const char *, struct passwd *, char *,
                              size_t, struct passwd **);
           struct passwd *getpwuid(uid_t);
           int            getpwuid_r(uid_t, struct passwd *, char *,
                              size_t, struct passwd **);
