wcscat - Man Page

concatenate two wide-character strings


#include <wchar.h>

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


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

The strings may not overlap.

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

Return Value

wcscat() returns dest.
