[gameprogrammer] Re: Linux _findfirst equivalent

Hi,

Kevin Jenkins schrieb:
This code is supposed to add all non-hidden files and files in subdirectories from applicationDirectory/subDirectory through the member function AddFile
The attached file shows how to search through a directory for files. It supports "*.xxx" notation and the search string may contain a sub directory. It doesn't do exactly what your source is doing, but the missing thing (searching through sub directories) is only a small change. I could do that, if required?
