Remarks

getdisk gets the current drive number. It returns an integer: 0 for A, 1 for B, 2 for C, and so on (equivalent to DOS function 0x19).

setdisk sets the current drive to the one associated with drive: 0 for A, 1 for B, 2 for C, and so on (equivalent to DOS call OxOE).

Return value

getdisk returns the current drive number. setdisk returns the total number of drives available.

Example

#include <stdio.h>
#include <dir.h>
int main(void)
{
   int disk, maxdrives = setdisk(2);
   disk = getdisk 0 + 'A' ;
   printf("\nThe number of logical drives  is:%d\n", maxdrives);
   printfC'The current drive is: %c\n", disk) ;
   return 0;
