Thread: Directory MP3 Search

sizeof(HANDLE ) is (so far always) the same as sizeof(void *), so a HANDLE in a 64 bit program is 64 bits not 32.

This is something I had saved in my hardrive cpp reference code directory, I forgot where it came from. No windows code even needed.

Code:

#include <iostream>
#include <dirent.h>


int main()
{

    std::string path = "./";

    DIR *d = opendir(path.c_str());
    struct dirent *dir;


    if(d)
    {
        while ((dir = readdir(d)) != NULL)
        {
            std::cout << dir->d_name << std::endl;
        }
        closedir(d);
    }
    
    std::cin.get();
    return 0;
}

I guess you can save all the names of files as variables and if the file does not have an extension then it is a directory and just use recursion and the loop again untill it has gone through all the subdirectories.

int, int32

What's the difference between int and int32? They're both 32 bits (4 bytes).

size of int depends of the compiler (and may - on target system)
size of int32 - always 32 bit

I will probably never use a 16bit compiler, so... there's no real difference to most of us. Unless int is defined as 64bit.

64bit compilers are available

Or you might run a quick VB app to test some C++ COM code, (both written using the same IDE) and expect an int to hold the same magnitude in both......oops


Point is, the size of an int is not a constant.
