I come from a C# background and I am working on a C++ project. I need to open files in a directory, then process that data in the files. The problem is on my target environment (Greenhills Integrity), I cannot access a “directory”. It seems C++ does not have a concept of a directory. Why not? This problem is simple in C#. I cannot link to any big library(BOOST or dirent) to get the files. I can open a file using fopen, but I won’t always know the file names, so I have to “strcat” the directory to each filename in order to “fopen” the files.
I need a way to just get the file names in a directory without using an external API. Is that possible?
No, it’s not possible. C++ has no “built-in” directory functionality – you need to use a library of some sort.
