FUNCTION

        <<wcpcpy>>---copy a wide-character string returning a pointer to its end

ANSI_SYNOPSIS

        #include <wchar.h>

        wchar_t *wcpcpy(wchar_t *<[s1]>, const wchar_t *,<[s2]>);

TRAD_SYNOPSIS

        wchar_t *wcpcpy(<[s1]>, <[s2]>

        wchar_t *<[s1]>;

        const wchar_t *<[s2]>;

DESCRIPTION

        The <<wcpcpy>> function copies the wide-character string pointed to by

        <[s2]> (including the terminating null wide-character code) into the

        array pointed to by <[s1]>. If copying takes place between objects that

        overlap, the behaviour is undefined.

RETURNS

        This function returns a pointer to the end of the destination string,

        thus pointing to the trailing '\0'.

PORTABILITY

<<wcpcpy>> is a GNU extension.

No supporting OS subroutines are required.
