As per documentation: "The debug versions of these functions first fill the buffer with 0xFD. To disable this behavior, use _CrtSetDebugFillThreshold." This is to make buffer overruns easier to spot under debugger. If you see a variable unexpectedly overwritten with 0xFD pattern, chances are high you are passing incorrect buffer length to strcpy_s or similar, and the buffer happens to be located in memory right before that varible. -- Igor Tandetnik _______________________________________________ sqlite-users mailing list [email protected] http://sqlite.org:8080/cgi-bin/mailman/listinfo/sqlite-users
