Hi. I thought the other gurus will answer this, but
since no one has answered, here goes...


the int386 fn. is for calling an interrupt. Interrupt
calling is only valid in REAL mode. pmode interrupts
are a different story all together. However in REAL
mode, as the syntax says:

int386(REGS in, REGS out, intno);

the first REGS var. "in", holds the input values of
registers. Using this u can set the values of the CPU
registers before calling an interrupt. The ISR will
use these values and do whatever func. is specified by
them. Generally register AX holds the function to be
executed, and BX holds the sub-function, if present. 

The "out" variable, is used to store the values of the
CPU registers after the ISR has finished. the ISR may
use the CPU registers to return any status info or
some pointers, or anything.

hope this helps...
btw, in case u dont know... ISR=Interrupt Service
Routine. It is the function assigned to an Interrupt
(software or hardware).

Nikhil.
