UPSCLI_UPSERROR(3)
==================

NAME
----

upscli_upserror - Get current error number for connection

SYNOPSIS
--------

 #include <upsclient.h>

 int upscli_upserror(UPSCONN_t *ups);

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

The *upscli_upserror*() function takes the pointer 'ups' to a
`UPSCONN_t` state structure and returns the value of the internal error
number, if any. 

This is typically used to check for certain error values like
`UPSCLI_ERR_UNKCOMMAND`.  That specific error can be used for detecting
older versions of linkman:upsd[8] which might not support a given command.

Some error messages have additional meanings, so you should use
linkman:upscli_strerror[3] to obtain readable error messages.

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

The *upscli_upserror*() function returns one of the `UPSCLI_ERR_*`
values from `upsclient.h`, or 0 if no error has occurred.
