hi all…
I extend ruby with C.
I m new to these kind of stuffs…
I integrate my dll namely prov.all into C program namely prov.c
afterthat i call those c functions through ruby .
irb(main):001:0> require ‘prov1’
=> true
irb(main):002:0> include Prov
=> Object
irb(main):003:0> Prov::load
=> true
irb(main):004:0> Prov::init_engine
(irb):4: [BUG] Segmentation fault
ruby 1.8.6 (2007-03-13) [i386-mswin32]
when i call Prov::init_engine method it gets crashed.
could you pls point me out which causes segmentation Problem.
Thanks in advance.
below is my prov1.c code
#include “windows.h”
#include “ruby.h”
#include “prov.h”
#define _D(string) {OutputDebugString(string);}
VALUE Prov;
void _textline(const char s, int len)
//***********************************
{
_D(s);
}
static VALUE p_load(VALUE self )
//******************************
{
prov_load();
return Qtrue;
}
static VALUE p_init(VALUE self)
//*****************************
{
_D("-> init");
prov_set_textline_callback(_textline);
prov_renderInit();
//return Qtrue;
}
static VALUE p_parse(VALUE self, VALUE string_to_parse)
//*****************************************************
{
_D(StringValuePtr(string_to_parse));
return prov_parse(StringValuePtr(string_to_parse));
}
static VALUE pr_render( VALUE self )
//**********************************
{
_D("-> render");
prov_render(0);
//return Qtrue;
}
void Init_prov1()
//***************
