WCPCPY(3)               Linux Programmer's Manual              WCPCPY(3)

NAME         top

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

SYNOPSIS         top

       #include <wchar.h>

       wchar_t *wcpcpy(wchar_t *restrict dest, const wchar_t *restrict src);

   Feature Test Macro Requirements for glibc (see
   feature_test_macros(7)):

       wcpcpy():
           Since glibc 2.10:
               _POSIX_C_SOURCE >= 200809L
           Before glibc 2.10:
               _GNU_SOURCE

DESCRIPTION         top

       The wcpcpy() function is the wide-character equivalent of the
       stpcpy(3) function.  It copies the wide-character string pointed
       to by src, including the terminating null wide character (L'\0'),
       to the array pointed to by dest.

       The strings may not overlap.

       The programmer must ensure that there is room for at least
       wcslen(src)+1 wide characters at dest.

RETURN VALUE         top

       wcpcpy() returns a pointer to the end of the wide-character
       string dest, that is, a pointer to the terminating null wide
       character.
