wcsncat man page

wcsncat ā€” concatenate two wide-character strings


#include <wchar.h>

wchar_t *wcsncat(wchar_t *dest, const wchar_t *src, size_t n);


The wcsncat() function is the wide-character equivalent of the strncat(3) function. It copies at most n wide characters from the wide-character string pointed to by src to the end of the wide-character string pointed to by dest, and adds a terminating null wide character (L'\0').

The strings may not overlap.

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

Return Value

wcsncat() returns dest.
