UPSCLI_READLINE(3)
|
|
==================
|
|
|
|
NAME
|
|
----
|
|
|
|
upscli_readline - read a single response from a UPS
|
|
|
|
SYNOPSIS
|
|
--------
|
|
|
|
#include <upsclient.h>
|
|
|
|
int upscli_readline(UPSCONN_t *ups, char *buf, size_t buflen);
|
|
|
|
DESCRIPTION
|
|
-----------
|
|
The *upscli_readline()* function takes the pointer 'ups' to a
|
|
`UPSCONN_t` state structure, receives a single line from the server, and
|
|
copies up to 'buflen' bytes of the response into the buffer
|
|
'buf'.
|
|
|
|
Some parsing of the string occurs during reception. In particular,
|
|
ERR messages from linkman:upsd[8] are detected and will cause this
|
|
function to return -1.
|
|
|
|
RETURN VALUE
|
|
------------
|
|
|
|
The *upscli_readline()* function returns 0 on success, or -1 if an
|
|
error occurs.
