Re: XS hacking

Hi,Andreas are thous types in you type map. If they are what are they typed
as?

Also:
char *
glGetString( name )
 GLenum name
 CODE:
   glGetString(name);

should be

char *
glGetString( name )
 GLenum name
 CODE:
  RETVAL= glGetString(name);
OUTPUT:
   RETVAL


This is because your function is 'expecting' (it easier to explain it this
way) a char*.
