wcscat(3) Library Functions Manual wcscat(3)

wcscat - concatenate two wide-character strings

Standard C library (libc, -lc)

#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.

wcscat() returns dest.

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