Variable Documentation

initializer_normal

const mutex::attributes os::rtos::mutex::initializer_normal

static

Default normal mutex initialiser.

This variable is used by the normal mutex default constructor.

Definition at line 301 of file os-mutex.h.

initializer_recursive

const mutex::attributes_recursive os::rtos::mutex::initializer_recursive

static

Default recursive mutex initialiser.

This variable is used by the recursive mutex default constructor.

Definition at line 350 of file os-mutex.h.

max_count

constexpr count_t os::rtos::mutex::max_count = 0xFFFF

staticconstexpr

Constant with the maximum value for the recursion counter.

Definition at line 197 of file os-mutex.h.
