NAME
nng_cv_wake - wake all waiters
SYNOPSIS
DESCRIPTION
The nng_cv_wake() wakes any threads waiting for the condition variable cv
to be signaled in the nng_cv_wait() or
nng_cv_until() functions.
The caller must have have ownership of the mutex that was used when cv was allocated.
| The caller should already have set the condition that the waiters will check, while holding the mutex. |
This function wakes all threads, which is generally safer but can
lead to a performance problem when there are many waiters, as they are all
woken simultaneously and may contend for resources.
See nng_cv_wake1() for a solution to this problem.
