osSpTaskLoad
Format#include <ultra64.h>
void osSpTaskLoad(OSTask *task);
What These Functions Do
The osSpTaskLoad, osSpTaskStartGo, osSpTaskStart, osSpTaskYield, and osSpTaskYielded functions manage the signal processor (SP) "tasks" that can be invoked from the CPU host.
Tasks are embodied by an OSTask structure. Please see the OSTask page for information about that structure's members.
Following the completion of a task, the SP interrupts the CPU and generates an OS_EVENT_SP event. The application can associate a message queue with this event with the osSetEventMesg call. Furthermore, graphics task display lists should complete with a call to gDPFullSync to additionally cause the display processor (DP) to interrupt the CPU. The associated event for osSetEventMesg is OS_EVENT_DP.
The osSpTaskLoad function loads the given task into the SP. Before calling it, you must ensure that the SP is not currently executing. If this is a brand new task, the OSTask structure members need to initialized by the application.
