[aspect-devel] mktemp failure

[Timo Heister]

The following code seems to work and does not delete the file. Is
using /tmp/ always a good idea, though?

#include <stdlib.h>
#include <stdio.h>
#include <string.h>

int main()
{
  char pattern[256];
  strcpy(pattern, "/tmp/XXXXXX");

  int fd=mkstemp(pattern);
  if (fd==-1)
    {
      printf("mkstemp failed\n");
      return -1;
    }

  FILE *f=fdopen(fd, "w+");

  printf("%s\n",pattern);


  fprintf(f,"hi\n");

// to delete:  unlink(pattern);

  fclose(f);
}
