__strcpy_chk -- copy a string, with buffer overflow checking


#include <string.h>

char * __strcpy_chk(char * dest, const char * src, size_t destlen);


The interface __strcpy_chk() shall function in the same way as the interface strcpy(), except that __strcpy_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 __strcpy_chk() function is not in the source standard; it is only in the binary standard.
