/*This function is for dir browse. And it is based on turbo C.

The first parameter is the direct which is to be browsed. For example: "c:\turboc\11\".

The second parameter is the special file require. For example: "*.txt".

This function browse all files in this dir, including subdir.

The last but six line is make dir in the current dir.

If want to get current dir, you can use the getcurdir(0,buf) function.
