void QF_run

(

void

)

Transfers control to QF to run the application.

QF_run() implemetns the simple non-preemptive scheduler. QF_run() must be called from your startup code after you initialize the QF and define at least one active object control block in QF_active[].

Note:

When the Quantum Kernel (QK) is used as the underlying real-time kernel for the QF, all platfrom dependencies are handled in the QK, so no porting of QF is necessary. In other words, you only need to recompile the QF platform-independent code with the compiler for your platform, but you don't need to provide any platform-specific implementation (so, no qf_port.c file is necessary). Moreover, QK implements the function QF_run() in a platform-independent way, in the modile qk.c.

void QK_schedule_

(

void

)

The QK scheduler.

Note:

The QK scheduler must be always called with interrupts locked. The scheduler might unlock the interrupts internally, but always returns with interrupts locked.
