wcscat—concatenate two wide-character strings #include <wchar.h>
wchar_t *wcscat(wchar_t *s1, const wchar_t *s2);
Description
The wcscat function appends a copy of the wide-character string
pointed to by s2 (including the terminating null wide-character
code) to the end of the wide-character string pointed to by s1.
The initial wide-character code of s2 overwrites the null
wide-character code at the end of s1. If copying takes place between
objects that overlap, the behaviour is undefined.
Returns
The wcscat function returns s1;
no return value is reserved to indicate an error.
Portability
wcscat is ISO/IEC 9899/AMD1:1995 (ISO C).
No supporting OS subroutines are required.
