Simple Virtual Filesystem in C/C++

Question

I would like to implement a very simple Virtual Filesystem (VFS) which supports some basic file system operation like fwrite, fopen, fput, etc. The VFS is an abstraction lay

Answer 1

I don't think you can compile a module for different OSes, the way you want.

// Make the distinction at compile time,

FILE VFS_File_Open( const unsigned char strFile, int flags )
{
#ifdef _WINDOWS
    //implement here the system calls required to open a file on a WIN OS
#endif
#ifdef _LINUX
    //implement here the system calls required to open a file on a Linux OS
#endif
    etc
}
