set_rm_interrupt

Set real mode interrupt handler.

Declaration

Source position: go32.pp line 138

function set_rm_interrupt(

vector: Byte;

const intaddr: tseginfo

):Boolean;

Description

Sets a real mode interrupt handler.

Parameters:

vector: the interrupt vector number to set.
intaddr: address of new interrupt vector.

Return values: True if successful, otherwise False.

Remark:

The address supplied MUST be a real mode segment address, not a selector:offset address. So the interrupt handler must either reside in dos memory (below 1 Mb boundary) or the application must allocate a real mode callback address with get_rm_callback.

Errors

Check the int31error variable.

get_rm_interrupt		Get real mode interrupt vector.
set_pm_interrupt		Set protected mode interrupt handler.
