The simplest solution would be

Код:

valstr(buf, strval(buf) + 1);
fwrite(handle, buf);

instead of

Код:

fwrite(handle, strval(buf) + 1);

This will compile but it will crash the server (or not write the line).

You open the file with mode io_read, but still attempt to write to it. Use io_readwrite.
