Description
Converts an integer value to a timespec.
Convert an absolute timespec into a tick timeout, taking into account queue flags.
Receive a message from a message queue with timeout. Please refer to http://pubs.opengroup.org/onlinepubs/9699919799/functions/mq_timedreceive.html for more details.
Send a message to a message queue with timeout. Please refer to http://pubs.opengroup.org/onlinepubs/9699919799/functions/mq_timedsend.html for more details.
Calculates the number of ticks between now and a given timespec.
Converts a struct timespec to FreeRTOS ticks.
Calculates pxResult = x + y.
Calculates pxResult = x - y.
This is a POSIX function, please refer to the POSIX specification for a detailed description. Note the following three deviations/issues originating from the underlying FreeRTOS implementation: * The time value passed by abstime will be rounded up to the next FreeRTOS tick. * The actual timeout will happen after the tick the time was rounded to and before the following tick. * It is possible, though unlikely, that the task is preempted directly after the timeout calculation, delaying timeout of the following blocking operating system call by the duration of the preemption.
Calculates pxResult = x + ( struct timespec ) nanosec.
