osSpTaskStart
Syntax
#include <ultra64.h>
s32 osSpTaskStart(OSTask *task);
Explanation
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 osSpTaskStart macro calls the osSpTaskLoad, and then calls the osSpTaskStartGo function.
