SysBase

I am stuck on this, updating from OS3.9 to 4.1FE:

struct Process *ThisProcess=NULL;
 
ThisProcess=((struct ExecBase *)SysBase)->ThisTask;
if (ThisProcess->pr_CLI)
{
// get command line args
}
 
 
// disable requesters
wptr=ThisProcess->pr_WindowPtr;
ThisProcess->pr_WindowPtr=(APTR)-1L;

The first call gives me GCC warning 'assignment from incompatible pointer type'. Since the first one doesn't work correctly, the second one crashes when I go to block the system requesters (Please insert volume "xxx") What is the correct OS4 code for this?

Something like that: struct

Something like that:

struct Process *ThisProcess=(struct Process *)IExec->FindTask(NULL);
...
APTR oldvalue = IDOS->SetProcWindow((APTR)-1L);

ThisProcess=((struct ExecBase

ThisProcess=((struct ExecBase *)SysBase)->ThisTask;

This is not allowed anyway. Use ThisProcess = FindTask(NULL); instead. Furthermore moving a task pointer to a process pointer should give an incompatible pointer warning. This is correct: ThisProcess = (struct Process *) FindTask(NULL);
