upscli_splitaddr
UPSCLI_SPLITADDR(3) NUT Manual UPSCLI_SPLITADDR(3)
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 raw UPS definition buf and returns pointers to dynamically allocated memory in
upsname and 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) 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.
