UPSCLI_SENDLINE(3)
==================

NAME
----

upscli_sendline, upscli_sendline_timeout - send a single command to a UPS

SYNOPSIS
--------


 #include <upsclient.h>

 int upscli_sendline(UPSCONN_t *ups, const char *buf, size_t buflen);
 int upscli_sendline_timeout(UPSCONN_t *ups, const char *buf, size_t buflen, unsigned int timeout);

DESCRIPTION
-----------

The *upscli_sendline()* and *upscli_sendline_timeout()* functions take the
pointer 'ups' to a `UPSCONN_t` state structure and transmit a buffer 'buf' of
size 'buflen' to the server.

The data in 'buf' must be a fully formatted protocol command as no
parsing of the buffer occurs within this function.

The difference between the two functions is that *upscli_sendline_timeout()*
lets the caller decide the amount of time ('timeout' seconds) after which it
should give up and return, whereas *upscli_sendline()* does not offer this
freedom, and uses an immediate timeout (0 second).

RETURN VALUE
------------

The *upscli_sendline()* and *upscli_sendline_timeout()* functions return 0 on
success, or -1 if an error occurs.
