I need to adapt a file written in Borland C Builder 5 to be usable in MS Visual Studio 2022. One of the files heavily utilizes the dir.h library, which, as far as I can tell, is a C library exclusive to Builder. The source files are available, however they have a lot of dependencies and, as I've mentioned, are written in C. I have searched the Internet for a substitute, unfortunately to no avail. Does a similar library exist for C ? Or do I have to re-write the file (which is pretty big) using e.g. std::filesystem?

CodePudding user response：

The functions in dir.h are mapping quite direct to Win32 API calls of fileapi.h. You could use this header for a quick port.

For a modernization it might be the best idea to re-write the code using std::filesystem. There is hardly any sensible C library with such a C-like API.

Well there are the modernized Embarcadero API-calls in System.SysUtils.hpp. But they are still no modern C and they are only available their ecosystem.
