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.
