__wmemmove_chk

Name

__wmemmove_chk -- copy an array of wide-characters, with buffer overflow checking

Synopsis

#include <wchar.h>

wchar_t * __wmemmove_chk(wchar_t * s1, const wchar_t * s2, size_t n, size_t ns1);

Description

The interface __wmemmove_chk() shall function in the same way as the interface wmemmove(), except that __wmemmove_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 ns1 specifies the size of the object pointed to by s1. If n exceeds ns1, the function shall abort and the program calling it shall exit.

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