# zmq_strerror(3) Manual Page

## NAME

zmq_strerror - get 0MQ error message string

## SYNOPSIS

const char *zmq_strerror (int errnum);

## DESCRIPTION

The zmq_strerror() function shall return a pointer to an error message string corresponding to the error number specified by the errnum argument. As ØMQ defines additional error numbers over and above those defined by the operating system, applications should use zmq_strerror() in preference to the standard strerror() function.

## RETURN VALUE

The zmq_strerror() function shall return a pointer to an error message string.

## ERRORS

No errors are defined.

## EXAMPLE

Displaying an error message when a ØMQ context cannot be initialised

    void *ctx = zmq_init (1, 1, 0);
    if (!ctx) {
        printf ("Error occurred during zmq_init(): %s\n", zmq_strerror (errno));
        abort ();
    }
