#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.
