types.h
Various system types.

trn_condvar_create
void trn_condvar_create(trn_condvar_t *condvar)
Creates a condition variable.

trn_condvar_wait
result_t trn_condvar_wait(trn_condvar_t *condvar, trn_mutex_t *mutex, uint64_t timeout) REQUIRES(mutex)
Waits for the condition variable to be signalled.

trn_condvar_signal
result_t trn_condvar_signal(trn_condvar_t *condvar, int n)
Signals n threads waiting on the condition variable, or -1 for all of them.

result_t
uint32_t result_t
Function result.
