* Name: irq_foreach
|
|
*
|
|
* Description:
|
|
* This function traverses the internal list of interrupts and provides
|
|
* information about each attached interrupt.
|
|
*
|
|
* Some caution may be necessary: If interrupts are disabled then the
|
|
* counts may change during the traversal. If pre-emption is enabled, then
|
|
* the traversed sequence may be widely separated in time.
|
|
*
|
|
* Input Parameters:
|
|
* callback - This function will be called for each attached interrupt
|
|
* along with the IRQ number, an instance of struct irq_info_s,
|
|
* and the caller provided argument
|
|
* args - This is an opaque argument provided with each call to the
|
|
* callback function.
|
|
*
|
|
* Returned Value:
|
|
* Zero (OK) is returned after callback has been invoked for all of
|
|
* the attached interrupts. The callback function may terminate the
|
|
* traversal at any time by returning a non-zero value. In that case,
|
|
* irq_foreach will return that non-zero value.
