How to use the Ctrl?

[GuyZana]

Hello my friend,
I'm programming now a little software in C for dos,
i need to know how to do these things:
1. i'm using biokey() to read a key that pressed but instead
for waiting for a key i'm reading a key whenever a key is
pressed: like this:
if (bioskey(1))
key = bioskey(0);

i know the modifires(ctrl) are in bioskey(2) i deed this:
if (bioskey(1))
{
modifiers = bioskey(2); // check the modifiers
key = bioskey(0); // if key pressed than save it to key
}
and than i'm checking the modifires, but it doesn't work
if you know how to get the modifires please tell me

2. i have this problem with wav files, when the mouse is
working and there is wav playing my prog is getting stuck
i probably need to declare some where about critical task:
cti; but i don't know where and how, if you know please
tell me

Thanks from advanced,
Guy Zana

The CTRL, ALT, SHIFT etc... are some special keys that dont really call the interrupt unless some other key is pressed. Their state is stored in the keyboard buffer

0x00417 and 0x00418 hex hold the status of these keys. YOu can use a far pointer to access the values in here...
