NAME
nng_cv_alloc - allocate condition variable
SYNOPSIS
DESCRIPTION
The nng_cv_alloc()
function allocates a condition variable, using
the mutex mtx, and returns it in cvp.
Every condition variable is associated with a mutex, which must be
owned when a thread waits for the condition using
nng_cv_wait()
or
nng_cv_until()
.
The mutex must also be owned when signaling the condition using the
nng_cv_wake()
or
nng_cv_wake1()
functions.
RETURN VALUES
This function returns 0 on success, and non-zero otherwise.
