Exemple #1

static void SetupTrace( struct TDebugThread *obj )
{
    int update = FALSE;
    Tss tss;
    unsigned char ch = 0;

    obj->FDebug = FALSE;
    obj->FWasTrace = TRUE;

    RdosGetThreadTss( obj->ThreadID, &tss );

    RdosReadThreadMem( obj->ThreadID, tss.cs, tss.eip, (char *)&ch, 1 );

        update = TRUE;
    }

    if( ( tss.eflags & 0x100 ) == 0 ) {

        update = TRUE;
    }

    if( update )
