Detailed Description

Thread control block.

This structure holds current status of the thread.

Field Documentation

◆ block_object

unsigned long OS_thread_t::block_object

Identification of object, which causes this thread to block.

This value if context-dependent. If thread is blocked joining other thread, then this contains thread ID. If thread is blocked waiting for mutex, then this contains mutex address.

◆ exit_status

int OS_thread_t::exit_status

Exit status after thread quit.

◆ priority

uint8_t OS_thread_t::priority

Thread priority.

This is used by scheduler to decide which thread to run.

◆ process_id

Process_t OS_thread_t::process_id

Owning process reference.

◆ rpc_stack

OS_RPC_stack OS_thread_t::rpc_stack

Ummmmm...

◆ signal_handler

void(* OS_thread_t::signal_handler) (int)

Address of signal handler to use.

◆ signals

uint32_t OS_thread_t::signals

Current pending signal bitmask.

Each set bit means that one signal has been delivered.

◆ sp

unsigned long* OS_thread_t::sp

Value of SP.

This is only valid if thread is in state different than THREAD_STATE_RUNNING. Obviously it is undefined for empty thread slots and slots which don't have stack allocated yet.

◆ stack_id

uint8_t OS_thread_t::stack_id

ID of stack, which is allocated to this thread.

◆ state

enum ThreadState OS_thread_t::state

State of this thread.
