Set real mode interrupt handler
Source position: go32.pp line 124
function set_rm_interrupt( |
vector: Byte; |
const intaddr: tseginfo |
):Boolean; |
Sets a real mode interrupt handler.
Parameters:
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. |
Check the int31error variable.
