Open rexxsyslib.library
Posted: Sat Sep 17, 2011 8:19 pm
The following and similar code opens the given library (with or without the _NOBLOBALIFACE_
the code following does not open the rexxsyslib.library (with or without the _NOGLOBALIFACE_
the Base and IFace defintione are taken from <proto/rexxsyslib.h>
What is happening here?
Code: Select all
//#define _NOGLOBALIFACE_
#define __USE_INLINE__
#define MINVERSION 52
#include <stdio.h>
#include <proto/asl.h>
#include <proto/exec.h>
#include <exec/types.h>
#include <exec/exec.h>
#include <exec/execbase.h>
#include <interfaces/exec.h>
struct Library *AslBase;
struct AslIFace *IAsl;
int main ()
{
AslBase = OpenLibrary ("asl.library",MINVERSION);
if (AslBase)
IAsl = (APTR)GetInterface(AslBase, "main", 1L, NULL);
else printf("no AslBase\n");
printf("hello\n");
if (AslBase) CloseLibrary (AslBase); //changed
if (IAsl) DropInterface( (struct Interface *) IAsl);
}
