Generic thread functions.

These are C versions of functions provided in C++ via rtos::Thread and rtos::ThisThreadRead the current RTOS kernel millisecond tick count. The tick count corresponds to the tick count the RTOS uses for timing purposes. It increments monotonically from 0 at boot, so it effectively never wraps. If the underlying RTOS only provides a 32-bit tick count, this method expands it to 64 bits.

Returns

RTOS kernel current tick count

Note

Mbed OS always uses millisecond RTOS ticks, and this could only wrap after half a billion years.

In a non-RTOS build, this computes an equivalent time in milliseconds, based on a HAL timer. The time may be referenced as 0 on first call.

You cannot call this function from ISR context.

The equivalent functionality is accessible in C++ via rtos::Kernel::get_ms_count.

Sleep for a specified time period in millisec:

Parameters

millisec

time delay value

Note

You cannot call this function from ISR context.

The equivalent functionality is accessible in C++ via rtos::ThisThread::sleep_for.

Sleep until a specified time in millisec The specified time is according to Kernel::get_ms_count().

Parameters

millisec

absolute time in millisec

Note

You cannot call this function from ISR context.

if millisec is equal to or lower than the current tick count, this returns immediately.

The equivalent functionality is accessible in C++ via ThisThread::sleep_until.
