UTILS_TimespecToTicks() function

The timespec to convert.

Where the result of the conversion is stored. The result is rounded up for fractional ticks.

Converts an integer value to a timespec.

Convert an absolute timespec into a tick timeout, taking into account queue flags.

Checks that a timespec conforms to POSIX. A valid timespec must have 0 <= tv_nsec < 1000000000.

Calculates the number of ticks between now and a given timespec.

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.
