# zmq\_strerror(3)

get 0MQ error message string

## 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 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.

## 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 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 ();
}
```
