Check the enviroment variables.

Prm753 · Oct 19th, 2005, 3:04 PM

Umm, I know this is a stupid question, but how do I do that?

nnxion · Oct 19th, 2005, 3:45 PM

/* getenv example: getting path */
#include <stdio.h>
#include <stdlib.h>

int main ()
{
  char * buffer;
  buffer = getenv ("PATH");
  if (buffer!=NULL)
    printf ("Current path is: %s",buffer);
  return 0;
}

Taken right from here.

Arg........ the varibles don't work on my pc. One last question... I can't define the DeleteDirectory(); function in my code. How is this possible and is that the right code to delete a file?

Don't worry about Tempest, he's insane, bitchy, and suffers from man-PMS. A potent combination.

Is it a joke? You just revived a 7-month old thread.

uman · May 23rd, 2006, 12:28 AM

Oops. Mistake. Lock it if you like, mods.

Funny this is. PRM (the OP) has this thread in his signature as an example of how NOT to post a question. Now the same thread has an example of how NOT to revive a thread.
