Name

__wcscat_chk -- concatenate two wide-character strings, with buffer overflow checking

Synopsis

#include <wchar.h>

wchar_t * __wcscat_chk(wchar_t * dest, const wchar_t * src, size_t destlen);

Description

The interface __wcscat_chk() shall function in the same way as the interface wcscat(), except that __wcscat_chk() shall check for buffer overflow before computing a result. If an overflow is anticipated, the function shall abort and the program calling it shall exit.

The parameter destlen specifies the size of the object pointed to by dest.

The __wcscat_chk() function is not in the source standard; it is only in the binary standard.
