InterruptEnable()

Enable hardware interrupts

Synopsis:

#include <sys/neutrino.h>

void InterruptEnable( void );

Library:

libc

Description:

The InterruptEnable() function enables all hardware interrupts. It may be called from a thread or from an interrupt handler. Before calling this function the thread must request I/O privity by calling:

ThreadCtl( _NTO_TCTL_IO, 0 );

If the thread doesn't do this, it might SIGSEGV when InterruptUnlock() is called.

This function should be called as quickly as possible after an InterruptDisable() call.

Use InterruptLock() and InterruptUnlock() instead of InterruptDisable() and InterruptEnable(). The InterruptLock()/InterruptUnlock() functions perform the intended function on SMP hardware, and allow your interrupt thread to run on any processor in the system.

Classification:

QNX 6
