====== cpunum_set_input_line() ======
----
Set the logical state of an input line on a CPU.
===== Syntax =====
----
==== Declaration ====
Declared in ''src/emu/cpuint.h'' as

<code c++>void cpunum_set_input_line(running_machine *machine, int cpunum, int line, int state);</code>
==== Parameters ====
  * ''machine'' – Pointer to the machine where this CPU is running
  * ''cpunum'' – Index to the CPU
  * ''line'' – The IRQ to set, those are generally defined in the appropriate CPU header files
  * ''state'' – The logical state to set. Possible values are ''ASSERT_LINE'', ''HOLD_LINE'', ''CLEAR_LINE'' and ''PULSE_LINE''
==== Returns ====
Nothing.

===== Example =====
----
<code c++>cpunum_set_input_line(machine, 1, M6809_FIRQ_LINE, ASSERT_LINE);</code>
This call will change the state of the ''M6809_FIRQ_LINE'' of the second CPU to ''ASSERT_LINE'', meaning that the CPU will now take this interrupt if interrupts are enabled.
