Task Manager ena_dsp - Enable Dispatch

RTEMS ITRON 3.0 API User's Guide

1.4.8: ena_dsp - Enable Dispatch

CALLING SEQUENCE:

ER ena_dsp(void);

STATUS CODES:

E_OK - Normal Completion

E_CTX - Context error (issued from task-independent portions or issued after execution of loc_cpu)

DESCRIPTION:

This system call enables task dispatching, that is, it finishes dispatch disabled state caused by the execution of dis_dsp.

No error will result if a task which is not in dispatch disabled state issues ena_dsp. In this case, dispatching will just remain enabled.

An E_CTX error will result if ena_dsp is issued when both interrupt and dispatching are disabled with loc_cpu. (For details, see the description of loc_cpu.)
