Mbed Thread
[Platform]

Generic thread functions.

These are C versions of functions provided in C++ via rtos::Thread and rtos::ThisThread Read 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.

Definition at line 40 of file mbed_thread.cpp.

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.
