Function Documentation

XN_C_API XnStatus XN_C_DECL xnSchedulerAddTask ( XnScheduler pScheduler,
XnUInt64  nInterval,
XnTaskCallbackFuncPtr  pCallback,
void *  pCallbackArg,
XnScheduledTask **  ppTask 
)

Adds a task to the scheduler.

Parameters:
pScheduler[in] The scheduler to handle this task.
nInterval[in] The interval, in milliseconds, in which callback should be called.
pCallback[in] The function to be called when time arrived.
pCallbackArg[in] The argument that will be passed to the callback method.
ppTask[out] Upon successful return, holds a handle to the started task.
XN_C_API XnStatus XN_C_DECL xnSchedulerRemoveTask ( XnScheduler pScheduler,
XnScheduledTask **  ppTask 
)

Removes a task from the scheduler.

Parameters:
pScheduler[in] The scheduler this task is registered to.
ppTask[in/out] The task to be removed from the scheduler.
XN_C_API XnStatus XN_C_DECL xnSchedulerRescheduleTask ( XnScheduler pScheduler,
XnScheduledTask pTask,
XnUInt64  nInterval 
)

Changes scheduling of a specific task.

Parameters:
pScheduler[in] The scheduler this task is registered to.
pTask[in] The task to be removed from the scheduler.
nInterval[in] The new interval to be used.
XN_C_API XnStatus XN_C_DECL xnSchedulerShutdown ( XnScheduler **  ppScheduler)

Shuts down a scheduler thread. All timers on that scheduler will be stopped.

Parameters:
ppScheduler[in/out] A pointer to the scheduler to be shut down.
XN_C_API XnStatus XN_C_DECL xnSchedulerStart ( XnScheduler **  ppScheduler)

Starts a scheduler thread. Multiple timers can be added to the created scheduler.

Parameters:
ppScheduler[out] Upon successful return, holds a handle to created scheduler.
