void tor_locking_init | ( | void | ) |
Initialize the locking module, if it is not already initialized.

void tor_mutex_acquire | ( | tor_mutex_t * | m | ) |
Wait until m is free, then acquire it.

void tor_mutex_init | ( | tor_mutex_t * | m | ) |
Initialize mutex so it can be locked. Every mutex must be set up with tor_mutex_init() or tor_mutex_new(); not both.

void tor_mutex_init_nonrecursive | ( | tor_mutex_t * | m | ) |
As tor_mutex_init, but initialize a mutex suitable that may be non-recursive, if the OS supports that.

void tor_mutex_release | ( | tor_mutex_t * | m | ) |
Release the lock m so another thread can have it.

void tor_mutex_uninit | ( | tor_mutex_t * | m | ) |
Clean up the mutex m so that it no longer uses any system resources. Does not free m. This function must only be called on mutexes from tor_mutex_init().
Destroying a locked mutex is undefined behaviour. Global mutexes may be locked when they are passed to this function, because multiple threads can still access them. So we can either:
