Function RTKPreemptionsON

RTKernel-32 supports both cooperative and preemptive multitasking. Function RTKPreemptionsON enables preemptive scheduling:

void RTKPreemptionsON(void);

After initialization of RTKernel-32, preemptions are enabled automatically only if RF_PREEMPTIVE is set in RTKConfig.Flags.

Please refer to Multitasking, Real-Time, and RTKernel-32, What is Multitasking? and Advanced Topics, Preemptive or Cooperative Multitasking? for a detailed discussion of preemptive and cooperative scheduling.

RTKPreemptionsON is only supported if the interrupt driver supports task switches inside interrupt handlers. Use function RTKCanPreempt to check whether preemptions are supported.
