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.
