Concerning DJGPP 2... I need something like this.. __dpmi_paddr SelectorOffset32; DoINT(SelectorOffset32); //Simulate an interrupt by calling SelectorOffset32 (contains //a selector:offset32 pair). However, I can't seem to do it (through inline assembly). The assembly code is 'roughly' like this (not exact, because I really don't fully understand writing inline assembly code). inline void FarCall(__dpmi_paddr *SelectorOffset32) { asm(" pushf lcall (_SelectorOffset32) //I'm not sure how to put this. ) : : "m" SelectorOffset32 //Or this. :) :" } I'm really very unsure about that inline assembly code there. DJGPP 2 probably gave some big errors. (ugh!). Thanks for any help! PS: The reason for this is because I need to chain an original interrupt after hooking to it. I can't use _go32_chain_protected_mode_interrupt for some internal reasons. (I'm hooking to int 8h, and changing its speed). -- []----------------------------------------------------------[] | Kenneth Foo Here's the question of the year: | | kenfoo AT techm DOT pl DOT my Why do brains look like intestines? | []----------------------------------------------------------[]
