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