//      This file contains q.. counterparts of FILE* functions from Clib.
//      The only difference is that they set 'qerrno' variable too.
//      You should not use C standard I/O functions in your modules.
//      The reason: Borland keep FILE * information local to a DLL
//      so if you open a file in the plugin and pass the handle to the
//      kernel, the kernel will not be able to use it.
