Question: How to recursively store all files into a vector?

[Greg Williamson]

I'm trying to recursively search a folder for files and then store them into a vector for later use but my vector is coming up empty. if I cout resources inside the else it does list files though. Any ideas what I'm doing wrong?

include "tinydir.h"

include

include

typedef std::vectorstd::string fpathVec;
fpathVec sprites, rooms;

void get_files(std::string fpath, fpathVec vec)
{

tinydir_dir dir;
int i;

if (fpath.back() != '/')
    fpath += "/";

tinydir_open_sorted(&dir, fpath.c_str());

for (i = 0; i < dir.n_files; i++)
{
    tinydir_file file;
    tinydir_readfile_n(&dir, &file, i);

    if (file.is_dir)
    {
        if (strcmp(file.name, ".") != 0 && strcmp(file.name, "..") != 0)
        {
            get_files(fpath + file.name + "/", vec);
        }
    }
    else
    {
        std::string resource = fpath + file.name;
        vec.push_back(resource);
    }
}

tinydir_close(&dir);

}

int main()
{
get_files("../../gaym", sprites);
std::cout << sprites.size() << std::endl;
}

You're passing a copy of a std::vector into the function, so the original copy is never modified.

Change the function signature to this to pass a reference:

void get_files(std::string fpath, fpathVec &vec)
