[Dev-C++] CGI File Locking across server types

[Michael D. S. <for...@hi...>]

I notice that Dev C++ has fcntl.h. My UNIX book says fcntl is the only file 
lock that works ( is implemented ) across all UNIX platforms. Working on my 
home computer it seems that Windows always locks a file that's in use, but 
then this is not a server. About those I know nothing.

Dev C++ is a Windows version and it has fcntl so I'm "assuming" it's a 
Windows compatible implementation but, if so, does it still work if the 
executable is copied to a UNIX machine, or does it have to be compiled on 
the machine it's going to be ran on?

Anyone have any experience with this? Any advice?

Executables compiled on Windows will not work on Linux, the source has to be
recompiled for this. About your problem, it's a bit tricky, because _fmode()
is a function on some platforms and a variable on others. The best way to
handle this would be to use a wrapper function and conditional compilation
(#ifdef etc.).
