Typedef Documentation

QI_type

Typedef for enum _QI_type. The timeout types allow high resolution timeouts to be specified. If this option is not specified, only native (read ticks in VxWorks and all timeouts on POSIX platforms) are allowed. There are two basic pend types types: FIFO - tasks will be awakened on a FIFO basis PRIORITY - tasks will be awakened on PRIORITY basis. This controls how the wake-up order when multiple consumers pend on the same PL. In my estimation, this is not a good thing to do, so in almost all case the user should pick either QI_K_TYPE_PENDING or QI_K_TYPE_PENDING_WTO.
