__wcsrtombs_chk

Name

__wcsrtombs_chk -- convert a wide-character string to a multibyte string, with buffer overflow checking

Synopsis

#include <wchar.h>

size_t __wcsrtombs_chk(char * dest, const wchar_t * * src, size_t len, mbstate_t * ps, size_t destlen);

Description

The interface __wcsrtombs_chk() shall function in the same way as the interface wcsrtombs(), except that __wcsrtombs_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. If len exceeds destlen, the function shall abort and the program calling it shall exit.

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