Subject: [ruby-talk:02022] rb_global_entry



 I need to access ruby_errinfo and initially I've written (ruby_errinfo is
 not in ruby.h)

[...]
 extern VALUE ruby_errinfo;
[...]

 Finally I use rb_global_entry() but its definition is also not in ruby.h.
Is there another way to access this variable ?

 I want to do something like this :

aestivum% cat toto.c
#include <ruby.h>

static struct global_entry *errinfo;
static VALUE toto_eCatch;
static VALUE titi() { rb_raise(toto_eCatch, "ESSAI"); }
static VALUE t_catch() { return rb_gvar_get(errinfo); }

static VALUE
toto()
{
    VALUE c = rb_rescue(titi, 0, t_catch, 0);
    if (rb_obj_is_kind_of(c, toto_eCatch))
        rb_warn("OK kind_of");
    return Qtrue;
}

Init_toto()
{
    toto_eCatch = rb_define_class("TotoCatch", rb_eStandardError);
    errinfo = (struct global_entry *)rb_global_entry(rb_intern("$!"));
    toto();
}
aestivum%
