QK initialization.

QK_init() is called from QF_init() in qk.cpp. This function is defined in the QK ports.

The QK scheduler.

Note:

The QK scheduler must be always called with the interrupts locked and unlocks interrupts internally.

The signature of QK_schedule_() depends on the policy of locking and unlocking interrupts. When the interrupt lock key is not used (QF_INT_KEY_TYPE undefined), the signature is as follows:
void QK_schedule_(void);

However, when the interrupt key lock is used (QF_INT_KEY_TYPE defined), the signature is different:
void QK_schedule_(QF_INT_KEY_TYPE intLockKey);

For the internal use, these differences are hidden by the macro QK_SCHEDULE_.

The QK extended scheduler for interrupt context.

Note:

The QK extended exscheduler must be always called with the interrupts locked and unlocks interrupts internally.

The signature of QK_scheduleExt_() depends on the policy of locking and unlocking interrupts. When the interrupt lock key is not used (QF_INT_KEY_TYPE undefined), the signature is as follows:
void QK_scheduleExt_(void);

However, when the interrupt key lock is used (QF_INT_KEY_TYPE defined), the signature is different:
void QK_scheduleExt_(QF_INT_KEY_TYPE intLockKey);
