// NOTE: This structure is significantly different from what was in the
|
|
// original code. Watcom provides opendir/readdir/closedir implementations,
|
|
// that use Win32 FindFirstFile/FindNextFile under the hood, which in turn
|
|
// is designed to deal with patterns.
|
|
//
|
|
// The first attempt was to use `dirent` implementation by Toni Ronkko
|
|
// (https://github.com/tronkko/dirent), however it appears to be incompatible
|
|
// with what is provided by Watcom. Toni's implementation adds `*` wildcard
|
|
// unconditionally implying `opendir` accepts directory name only, which I
|
|
// guess is fine when your goal is compliance with POSIX implementation.
|
|
// However in Watcom `opendir` can handle file patterns gracefully. The problem
|
|
// can be seen during game startup when cleaning MAPS directory using
|
|
// MAPS\*.SAV pattern. Toni's implementation tries to convert that to pattern
|
|
// for Win32 API, thus making it MAPS\*.SAV\*, which is obviously incorrect
|
|
// path/pattern for any implementation.
|
|
//
|
|
// Eventually I've decided to go with compiler-specific implementation, keeping
|
|
// original implementation for Watcom (not tested). I'm not sure it will work
|
|
// in other compilers, so for now just stick with the error.
