Need to get a file list into an array of files ?

[OhNoNotAgain]

All,

Newish to C. On a UNIX box I want to execute an ls command and capture the files in an array of filenames.

Can someone please recommend a method and/or a good site for this type of function for Unix.

Thanks

Something like this?

#include <stdio.h>
#include <stdlib.h>
#include <unistd.h>


#define MAXLINES 15000
#define MAXLEN 250
char bufnames[MAXLINES][MAXLEN];

int main(int argc, char **argv) {
int y = 0;
FILE *pp;

     if (argc < 2) {
        printf(&quot;Error: need command name string\n&quot;);
        exit(1);
     }


     pp = popen(argv[1],&quot;r&quot;);

        if (!pp) {
            perror(&quot;popen()&quot;);
            exit(1);
        } else {
           while ( (fgets(bufnames[y],MAXLEN,pp)) != NULL) {
                    printf(&quot;%d: %s\n&quot;, y, bufnames[y]);
                    y++;
           }
        pclose(pp);
        } 

        
   
return 0;
}

Then you can use whatever command you want to
get the output you need.
I suggest find dirname -type f instead of ls.
