How to extract filename from path

Question

There should be something elegant in Linux API/POSIX to extract base file name from full path

Answer 1

My example (improved):

    #include 

    const char* getFileNameFromPath(const char* path, char separator = '/')
    {
        if(path != nullptr)
        {
            for(size_t i = strlen(path);  i > 0; --i)
            {
                if (path[i-1] == separator)
                {
                    return &path[i];
                }
            }
        }
    
        return path;
    }
