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 **);
           void           setpwent(void);
