zmq_strerror - Man Page

const char *zmq_strerror (int errnum);

The zmq_strerror() function shall return a pointer to an error message string corresponding to the error number specified by the errnum argument. As 0MQ 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.

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

No errors are defined.

Displaying an error message when a 0MQ 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 ();
}
