I think in the muimaster.library there is missing a MUI_Fault() function -
here is my implementaion of it (currently *without* locale.library support):
LONG MUI_Fault(LONG code, STRPTR header, STRPTR buffer, LONG len)
{
LONG headerlen;
static char errstr[][22] = {"OK",
"Out Of Memory",
"Out Of Gfx Memory",
"Invalid Window Object",
"Missing Library",
"No ARexx",
"Single Task"
};
headerlen = strlen(header);
if (headerlen > 0)
{
headerlen += 2;
}
buffer[0] = '\0';
switch (code)
{/* could be optimizied ! */
case MUIE_OK : if (len >= 3+headerlen)
{
strcpy(buffer,errstr[0]);
}
break;
case MUIE_OutOfMemory : if (len >= 12+headerlen)
{
strcpy(buffer,errstr[1]);
}
break;
case MUIE_OutOfGfxMemory : if (len >= 15+headerlen)
{
strcpy(buffer,errstr[2]);
}
break;
case MUIE_InvalidWindowObject : if (len >= 20+headerlen)
{
strcpy(buffer,errstr[3]);
}
break;
case MUIE_MissingLibrary : if (len >= 15+headerlen)
{
strcpy(buffer,errstr[4]);
}
break;
case MUIE_NoARexx : if (len >= 8+headerlen)
{
strcpy(buffer,errstr[5]);
}
break;
case MUIE_SingleTask : if (len >= 11+headerlen)
{
strcpy(buffer,errstr[6]);
}
break;
default : return(Fault(code,header,buffer,len));
}
if ((header != NULL) && (strlen(buffer) > 0))
{
strins(buffer,": "); /* SAS-C !! */
strins(buffer,header);
}
return((LONG)strlen(buffer));
}

muimaster.library/MUI_RequestA muimaster.library/MUI_RequestA
NAME
MUI_RequestA -- Pop up a MUI requester.
RESULT
0, 1, ..., N = Successive id values, for the gadgets
you specify for the requester. NOTE: The numbering
from left to right is actually: 1, 2, ..., N, 0.
In case of a problem (e.g. out of memory), the
function returns FALSE.
-----
FALSE == 0 - or am I wrong?
So a perfect MUI requester handling should look like this:
status = MUI_RequestA(App,NULL,0,"Title","*_Abort|_Quit",
"Do you really want to leave?",NULL);
switch (status)
{
case 0 : ioerr = IoErr();
if (ioerr != MUIE_OK)
{
/* error handling */
}
else
{
/* Quit button */
}
break;
case 1 : /* Abort button */
break;
}
(Strange!)
But this won't work, because MUI_RequestA will *NOT* make an SetIoErr()!!!
(I think so, because I always get back an 'Object not found' from IoErr())
Stefan - how about fixing this, because there could no correct error handling
of low memory (and something other strange) situations for MUI_RequestA!
To SetIoErr() will be backward compatible to older versions of MUIMaster.lib,
but I would preffer not longer to use 0 as return value for a button!

How must i make a call to a hook function from my custom
class, with gcc, and with other than gcc to make it easier to
compile for others ?
For interested people, i've put a new release of my ADocReader
MUI Auto Doc Reader
