| typedef void(*) intset_func(struct most_dev *dev, unsigned int interrupts, unsigned int mask, unsigned int *oldmask) |
Changes the interrupt mask. All bits that are set in mask are set as specified in interrupts.
interrupts and mask consists of the components which have to be modified with bit operators to get the requested effect. IOMLOCK_MASK, IEMAINT_MASK, IEMINT_MASK, IEGP_MASK, IESRX_MASK, IESTX_MASK, IEARX_MASK, IEATX_MASK and IECPFSM_MASK.

Returns the features, a bitwise combination of ...
Definition at line 221 of file most-base.h.
Manages the usage count of the device. If a device is opened, the usage count must be incremented. If it's closed, it must be decremented. Currently this is used to prevent the low modules from being unloaded if the device is opened (used) by a high module.

| void most_dev_free | ( | struct most_dev * | dev | ) |
Frees a most_dev structure. This frees the memory of the given pointer plus the dev->impl. It decrements also the device count which is the reason why this must be implemented as function (we avoid exporting the device_count variable here, and because we only need this in initializiation/deinitialization code, speed is no issue here).
