How do you a directory list, and load the filenames into an array?

[Guest_imported]

I have looked everywhere, and nothing.
I found for_each_file(), but it doesnt seem to work, or I'm screwing up the syntax.

I thought scandir(), but its only for unix.

I'm using DOS (win98), long file names, and DJGPP as the compiler.

I am wanting to scan a Directory for all filenames ending in .m3u, the put the result in an array of say names[10][40], so I can call them up later.

It someone could show me the proper syntax, and some short sample code, I would be very thankful.

declare a char pointer

char *command="dir/b c:\directory>a.txt";
ststem(command);

the system command runs the commands that run on DOS prompt. the redirection operator redirects the o/p to the file a.txt. dir/b lists all files in a dir without any description.

include stdlib.h or dos.h to run this command.

I hope this works

Hello,

use the findfirst() and findnext() functions to scan a directory.

Thank you all so very much, I don't think the windows.h example will work, as I will only be using the dos part of windows, with no gui running, but the system(command) looks promising,
I was kind of hoping for a cross-platform type of command, because I'd like to port it over to linux, but, without your help I'd have nothing at all.

Thank you guys.

You can use WinAPI without any windows or/and GUI. Just do not create windows. John Fill

Here is one possible solution using gcc. Fill in details where appropriate.

#include <sys/types.h>
#include <stdio.h>
#include <stdlib.h>
#include <dirent.h>

#define MAX 1000

int main()
{

DIR *dp;
struct dirent *dirp;
char *d[MAX];
int i, j;

if((dp = opendir(&quot;./&quot) == NULL) exit(1);

i = 0;
while((dirp = readdir(dp)) != NULL){
d = (char *) malloc(strlen(dirp->d_name)+1);
strcpy(d, dirp->d_name);
i++;
}

if(closedir(dp) < 0) exit(1);

printf(&quot;Directory Contents\n&quot;
for(j = 0; j < i; j++) printf(&quot;%s\n&quot;,d[j]);

return 0;

}

you can try this one

#include <stdio.h>
#include <string.h>
#include <io.h>


void printFilesDir(char *mypath);

//FILE *fp;

int main(){


	//char mypath[]=&quot;c:\\&quot;;
	char *mypath;


	//fp=fopen(&quot;c:\\test.txt&quot;,&quot;w&quot;);

	mypath=strdup(&quot;c:\\&quot;);

	printFilesDir(mypath);


	//fclose(fp);

	return 0;

}



void printFilesDir(char *mypath){


	long hsearch;
	struct _finddata_t findinfo;
	long success;
	char *buffer;
	char strtmp[1000];
	char spec[]=&quot;*.*&quot;;
	char root[1000];

	strtmp[0]=0;



	strcpy(root,mypath);

	if( mypath[strlen(root)-1] != '\\')
		strcat(root,&quot;\\&quot;);


	sprintf(strtmp,&quot;%s%s&quot;,root,spec);


	hsearch= _findfirst(strtmp, &findinfo );

	if(hsearch == -1)
		return;


	do{
    	buffer = strdup(findinfo.name);

    	if( (strcmp(buffer,&quot;.&quot;)) != 0 && (strcmp(buffer,&quot;..&quot;)) != 0){


    		if(findinfo.attrib & _A_SUBDIR){

				strtmp[0]=0;
				sprintf(strtmp,&quot;%s%s&quot;,root,buffer);

        		printFilesDir(strtmp);

    		}else
        		fprintf(stdout,&quot;%s%s\n&quot;,root,buffer);
        		//fprintf(fp,&quot;%s%s\n&quot;,root,buffer);

		}

		success = _findnext(hsearch, &findinfo);
	}while(success == 0);


	_findclose(hsearch);

}

You guys are making it too difficult, no offense.

system(&quot;dir /b *.m3u > m3udir.txt&quot

that will create a list of m3u files in the m3udir.txt file. You can then read each name out of the file and store them in your array respectively.

using system is a bad style of programming. Ion Filipski
