Create dos command: dir in c program.

#include “stdio.h”

#include “dos.h”

void main(int count,char *argv[])

{

  struct find_t q ;

  int a;

  if(count==1)

  argv[1]="*.*";

  a = _dos_findfirst(argv[1],1,&q);

  if(a==0)

  {

     while (!a)

   {

    printf("  %s\n", q.name);

    a = _dos_findnext(&q);

    }

  }

  else

  {

  printf("File not found");

  }

}

Save the above file as list.c, compile and execute the go to command mode (current working directory) and write: list *.c

To run the list command in all directories and drive you will have to give the path of current working directory in command mode.

Write:

C:tc\bin>PATH c:\tc\bin

Now press enter key. Now your list command will work in all directory and drive.
