Interrupt Constants (Windows Embedded CE 6.0)
1/5/2010
The following table shows the Interrupt Constants.
| Constant | Description |
|---|---|
OAL_INTR_DYNAMIC |
Specifies the use of non-static mapping of a SYSINTR to an IRQ will be used. |
OAL_INTR_FORCE_STATIC |
Indicates a request to force static mapping of an IRQ to a SYSINTR even if static mapping for the IRQ is already assigned. |
OAL_INTR_IRQ_MAXIMUM |
This value defines the maximum number of IRQs. If there is no limitation for this value in the OAL library, the Windows Embedded CE resource manager only supports 64 IRQs. |
OAL_INTR_IRQ_UNDEFINED |
Value returned for an IRQ that is not associated with a SYSINTR. |
OAL_INTR_STATIC |
Indicates a request for static mapping of a SYSINTR to an IRQ. If this is not the first request for a given IRQ, the function fails when this flag is used. |
OAL_INTR_TRANSLATE |
Specifies the use of the obsolete IOCTL_HAL_TRANSLATE_IRQ semantic. In this case, if static mapping exists for the IRQ, the function returns a mapped SYSINTR. Otherwise, it creates a new mapping. |
