# xs\_strerror(3)

get error message string

## NAME

xs\_strerror - get error message string

## SYNOPSIS

**const char \*xs\_strerror (int** *errnum***);**

## DESCRIPTION

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

## RETURN VALUE

The *xs\_strerror()* function shall return a pointer to an error message string.

## ERRORS

No errors are defined.

## EXAMPLE

**Displaying an error message when the context cannot be initialised**.

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