Hi boys :)
Is there any function whick allows me to read the files that there are in a directory? Have you understand me? I have a directory, here there are some files, I select them and play them... thank a lot for your help!

LIBC have the opendir,,readtdir,closedir function that perform this
Code: Select all
1. #include <stdio.h>
2. #include <sys/types.h>
3. #include <dirent.h>
4.
5. int main()
6. {
7. struct dirent *lecture;
8. DIR *rep;
9. rep = opendir("." );
10. while ((lecture = readdir(rep))) {
11. printf("%s\n", lecture->d_name);
12. }
13. closedir(rep);
14. }great!!! Excuse me, if I want to select the file how do i do? thank a lotsauron_le_noir wrote:LIBC have the opendir,,readtdir,closedir function that perform thisCode: Select all

Put the result of the readdir in a table or a linked list
and implement a GU that display it after this uset for example the up & down key
to navigate and the button X to selection.
See below a sample that perform this.

}Take this code that i've written for a packing tool , add the artistic part/event handling , also make the function "listFiles" recursive if you want , and you're ready to go...:
