Errorcodes are passed in 'ups->upserror' (and 'ups->syserrno'). Uh oh, we don't have a connection to an UPS yet when we call upscli_splitname() or upscli_splitaddr(). The upscli_strerror() function that is used to return the message in upscli_errlist[] needs a pointer to a UPSCONN structure also. The upscli_errlist[] is static, so there is no way to...

I want to use upsdebugx, upslogx in 'clients/upsclient.c', however this fails with the following error messages (I trimmed the path to the build directory to <path> in order to prevent line wrapping): <path>/clients/upsclient.c:941: undefined reference to `upsdebugx' <path>/clients/upsclient.c:910: undefined reference to `upslogx'
