# upscli\_splitaddr(3)

Split a listening address into its components

## NAME

upscli\_splitaddr - Split a listening address into its components

## SYNOPSIS

```
        #include <upsclient.h>
        int upscli_splitaddr(const char *buf, char **hostname,
                int *port)
```

## DESCRIPTION

The **upscli\_splitaddr()** function takes a pointer to the listening address definition *buf* and returns the pointer to dynamically allocated memory in *hostname*. It also copies the port number into *port*.

## FORMATTING

A listening address definition is specified according to this format:

```
<hostname>[:<port>]
```

Definitions without an explicit port value receive the default value of *3493*.

## MEMORY USAGE

You must [**free**(3)](/free/3.md) the pointer *hostname* when you are done with it to avoid memory leaks.

## RETURN VALUE

The **upscli\_splitaddr()** function returns *0* on success, or *-1* if an error occurs.
