              uid_t    pw_uid    Numerical user ID.

              char    *pw_shell  Program to use as shell.

       The gid_t and uid_t types shall be defined 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.

              struct passwd *getpwnam(const char *);
              struct passwd *getpwuid(uid_t);

              int            getpwnam_r(const char *, struct passwd *, char *,
                                 size_t, struct passwd **);
              int            getpwuid_r(uid_t, struct passwd *, char *,
                                 size_t, struct passwd **);

              void           endpwent(void);
              struct passwd *getpwent(void);
