WCPCPY(3) Linux Programmer's Manual WCPCPY(3)
NAME
wcpcpy - copy a wide-character string, returning a pointer to its end
SYNOPSIS
#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
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 terminat‐
ing 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.
