sOsEventNo

Description
• Waits for notification of the inter OS event specified by the inter OS event number (sOsEventNo).
• When an inter OS event was already reported when this function was executed, the user application restarts soon after the
inter OS event wait status.
• The specified timeout value is rounded (rounding up after the decimal point) to tick units. Specify a timeout value of 1 tick or
higher.
• When the same inter OS event was reported multiple times when this function was executed, the user application
processes them as a single inter OS event notification.
• When an inter OS event was reported when multiple tasks were waiting for the same inter OS event notification, only the
task that executed this function first receives the notification and restarts execution.
