UPSCLI_UPSERROR(3)                NUT Manual                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 upsd(8) which might not support a given command.

       Some error messages have additional meanings, so you should use
       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.
