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


#include <wchar.h>

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

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


Since glibc 2.10:

_POSIX_C_SOURCE >= 200809L

Before glibc 2.10:



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

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


For an explanation of the terms used in this section, see attributes(7).
