Hi,

I have a small program which i'm attempting to port from unix to dos. I 
installed Windows on a spare machine along with djgpp (2.03), and luckily 
it didn't take much editing to get it running.

I sent it to a couple of friends (running Win 2000 also), but it just hangs 
for them, apparently doing nothing. If anyone can shed any light it would 
be much appreciated.

At the moment all the program does is list all files in C:\, decending 
through each directory in turn. I've included it below :

#include <stdio.h>
#include <string.h>
#include <sys/types.h>
#include <sys/stat.h>
#include <sys/dir.h>

struct direct *DirEntryPtr;
DIR *DirPtr;
struct stat Stat;
char Path[500];

char *a[200000];
int top = -1;
int isempty() { return top == -1; }
int Tmp;

void push(char *c) { a[++top] = c; }
char *pop() { return a[top--];}
void get_dir(char *dir_name);


int main(void)
{
  puts("Started ....");
  get_dir("\\");

  while(top > -1) {
    char *top = pop();
    get_dir(top);
    free(top);
 }

}

 void get_dir(char *dir_name)
 {

 DirPtr = opendir(dir_name);
   while (1)  {

      DirEntryPtr = readdir(DirPtr);
      if (DirEntryPtr == 0) break;

      if (strcmp(DirEntryPtr->d_name,".") != 0 &&
          strcmp(DirEntryPtr->d_name,"..") != 0)  {
             Path[0] = 0;
             strcat(Path,dir_name);
             strcat(Path,"\\");
             strcat(Path,DirEntryPtr->d_name);
              Tmp = stat(Path,&Stat);

             if (S_ISDIR(Stat.st_mode)) {

              char *str = malloc(strlen(Path) + 1);
               strcpy(str, Path);
               push(str);

            }
        printf("  %s\n",DirEntryPtr->d_name);

      }
   }
}


I'm compiling it with :

        gcc -o whatever whatever.c

Then sending the whatever.exe off to friends for testing- I assume it will 
be standalone ?

Thanks

pete
