Under Windows 3.x, retrieving the current directory or changing directories was accomplished as:
getcwd( DirPath, sizeof( DirPath ) ); // 3.x
...
chdir( DirPath );
The equivalent operations under Windows 98/95/NT follow the same general formats, but with a change in the function names:
GetCurrentDirectory( sizeof( DirPath ), DirPath ); // 98/95/NT
...
SetCurrentDirectory( DirPath );
Notice that the order of the arguments has been reversed. The size of the buffer now precedes rather than follows the buffer variable.
