Expand description
@brief Waits on the condition variable releasing the mutex lock
Atomically releases the currently owned mutex, blocks the current thread waiting on the condition variable specified by @a condvar, and finally acquires the mutex again.
The waiting thread unblocks only after another thread calls k_condvar_signal, or k_condvar_broadcast with the same condition variable.
@param condvar pointer to a @p k_condvar structure @param mutex Address of the mutex. @param timeout Waiting period for the condition variable or one of the special values K_NO_WAIT and K_FOREVER. @retval 0 On success @retval -EAGAIN Waiting period timed out.
