/*******************************************************************************

*
* Description: Example of using the _mkdir() function in C to create a file
* system directory. The function is available on Windows machines/compilers
* using the direct.h library.

#include <stdio.h>
// the _mkdir() function is found in the direct.h library, and the function will
// set errno in the errno.h library if an error occurs
#include <direct.h>

// directory, uses a relative path. If the directory already exists (perhaps
// because we run the program twice), an error will occur.

// and report which has occurred if one of them has
