Re: GCC: fclose() Error

I would agree. 

In this instance however I might guess that windows is reusing file handle IDs whereas others machines are not?



Your code as a complete program...

#include "stdio.h"

int main(int argc, char **argv) {
  char c;
  FILE * f;
  f = fopen(argv[1], "r");
  fclose(f);
  FILE * f1;
  f1 = fopen(argv[1], "r");
  while ((c = fgetc(f)) != EOF){
  }
}
