InterruptEnable()

Enable hardware interrupts

Synopsis:

#include <sys/neutrino.h>

void InterruptEnable( void );

Library:

libc

Use the -l c option to qcc to link against this library. This library is usually included automatically.

Description:

The InterruptEnable() function enables all hardware interrupts. You can call it from a thread or from an interrupt handler. Before calling this function, the thread must request I/O privileges by calling:

ThreadCtl( _NTO_TCTL_IO, 0 );

If the thread doesn't do this, it might SIGSEGV when it calls InterruptEnable().

You should call this function as quickly as possible after calling InterruptDisable().

Classification:

QNX Neutrino

Safety:
Cancellation point	No
Interrupt handler	Yes
Signal handler	Yes
Thread	Yes
