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.

upscli_sendline(3),
