Field Documentation

◆ owner

kernel_pid_t mutex_t::owner

The current owner of the mutex or NULL

Note: Only available if module core_mutex_priority_inheritance is used.

If either the mutex is not locked or the mutex is not locked by a thread (e.g. because it is used to synchronize a thread with an ISR completion), this will have the value of NULL.

Definition at line 164 of file mutex.h.

◆ owner_calling_pc

uinttxtptr_t mutex_t::owner_calling_pc

Program counter of the call to mutex_lock that most recently acquired this mutex.

This is used when the module core_mutex_debug is used to debug deadlocks and is non-existing otherwise

Definition at line 174 of file mutex.h.

◆ owner_original_priority

uint8_t mutex_t::owner_original_priority

Original priority of the owner.

Note: Only available if module core_mutex_priority_inheritance is used.

Definition at line 182 of file mutex.h.

◆ queue

list_node_t mutex_t::queue

The process waiting queue of the mutex.

Must never be changed by the user.
