Detailed Description

Thread attributes.

Allow to assign custom attributes (like stack address, stack size, priority) to the thread.

To simplify access, the member variables are public and do not require accessors or mutators.

If the attributes are modified after the thread creation, the thread attributes shall not be affected.

POSIX compatibility

Inspired by pthread_attr_t from <pthread.h> (IEEE Std 1003.1, 2013 Edition).

Member Data Documentation

clock

rtos::clock* os::rtos::internal::attributes_clocked::clock = nullptr

inherited

Attribute with the address of the clock to be used for timeouts.

It may be one of os::rtos::sysclock, os::rtos::rtclock, or any other user object derived from class os::rtos::clock.

If nullptr, the default clock is os::rtos::sysclock.

Definition at line 615 of file os-decls.h.

th_enable_assert_reuse

bool os::rtos::thread::attributes::th_enable_assert_reuse = false

Definition at line 871 of file os-thread.h.

th_priority

priority_t os::rtos::thread::attributes::th_priority = priority::normal

Thread initial priority.

If 0, the default is thread::priority::normal.

A convenient and explicit variant to this attribute is to call thread::priority (priority_t) at the beginning of the thread function.

Definition at line 869 of file os-thread.h.

th_stack_address

void* os::rtos::thread::attributes::th_stack_address = nullptr

Address of the user defined storage for the thread stack.

If nullptr, the default is to dynamically allocate the stack.

Definition at line 845 of file os-thread.h.

th_stack_size_bytes

std::size_t os::rtos::thread::attributes::th_stack_size_bytes = 0

Size of the user defined storage for the thread stack, in bytes.

If 0, the default is thread::stack::default_size().

A convenient and explicit variant to this attribute is to call thread::stack::default_size (std::size_t) just before creating the thread. However mind setting this from different threads at the same time.
