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.
