nng_cv_alloc(3supp)

SYNOPSIS

#include <nng/nng.h>
#include <nng/supplemental/util/platform.h>

typedef struct nng_cv nng_cv;

int nng_cv_alloc(nng_cv **cvp, nng_mtx *mtx);

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.

ERRORS

NNG_ENOMEM

Insufficient free memory exists.
