Ruby1.9.1: やっぱりfcloseで落ちてるっぽい

RUBY WINDOWS

ASRに含まれているrubyは、たぶんruby-1.9.1-p0-i386-mswin32。
VC 9.0だとだめなのかな？

#include <stdio.h>
#include "ruby.h"

static VALUE myfunc(VALUE self) {
  FILE *f;
  char buf[256];

  f = fopen("C:/foo.txt", "r+b");
  fgets(buf, 256, f);
  printf("%s\n", buf);
  fclose(f);

  return Qnil;
}

__declspec(dllexport)
void Init_ruby19ext() {
  VALUE m;

  m = rb_define_module("Ruby19Ext");
  rb_define_module_function(m, "myfunc", myfunc, 0);
}
