Hello,
I'm wondering why fgetc() returns 0xff if called with /dev/null:
#include <stdio.h>
#include <stdlib.h>
int
main(void)
{
int c;
FILE *f;
f = fopen("/dev/null", "r");
if (c != EOF)
printf("%c\n", fgetc(f));
}
Hmmm, are you *sure* your code should not be written as follows:
#include <stdio.h>
#include <stdlib.h>
int
main(int argc, char **argv)
{
FILE *f;
int c;
f = fopen("/dev/null", "r");
if (f != NULL) {
c = fgetc(f);
if (c != EOF)
printf("%c\n", c);
else
printf("EOF encountered\n");
}
return (0);
}
