This file contains wrapper APIs for native thread primitives which Ruby interpreter uses.
Now, we only support pthread and Windows threads.
If you want to use Ruby's Mutex and so on to synchronize Ruby Threads, please use Mutex directly.

void rb_native_cond_broadcast | ( | rb_nativethread_cond_t * | cond | ) |
Signals a condition variable.
[out] | cond | A condition variable to ping. |
cond
gets signalled. void rb_native_cond_destroy | ( | rb_nativethread_cond_t * | cond | ) |
Destroys the passed condition variable.
[out] | cond | A condition variable to kill. |
cond
is no longer eligible for other functions. void rb_native_cond_initialize | ( | rb_nativethread_cond_t * | cond | ) |
Fills the passed condition variable with an initial value.
[out] | cond | A condition variable to initialise. |
cond
is updated to its initial state. void rb_native_cond_signal | ( | rb_nativethread_cond_t * | cond | ) |
Signals a condition variable.
[out] | cond | A condition variable to ping. |
cond
gets signalled. pthread_cond_signal(3posix)
says it can even be "impossible to avoid the unblocking of more than one thread blocked on a condition variable". Just brace spurious wakeups. void rb_native_cond_timedwait | ( | rb_nativethread_cond_t * | cond, |
rb_nativethread_lock_t * | mutex, | ||
unsigned long | msec | ||
) |
Identical to rb_native_cond_wait(), except it additionally takes timeout in msec resolution.
Timeouts can be detected by catching exceptions.
[out] | cond | A condition variable to wait. |
[out] | mutex | A mutex. |
[in] | msec | Timeout. |
rb_eSystemCallError | Errno::ETIMEDOUT for timeout. |
mutex
is owned by the current thread. mutex
is owned by the current thread. void rb_native_cond_wait | ( | rb_nativethread_cond_t * | cond, |
rb_nativethread_lock_t * | mutex | ||
) |
Waits for the passed condition variable to be signalled.
[out] | cond | A condition variable to wait. |
[out] | mutex | A mutex. |
mutex
is owned by the current thread. mutex
is owned by the current thread. void rb_native_mutex_destroy | ( | rb_nativethread_lock_t * | lock | ) |

[out] | lock | A mutex to lock. |
0 | lock is successfully owned by the current thread. |
EBUSY | lock is owned by someone else. |
