Historically, GEOM utilities (gpart(8), gstripe(8), gmirror(8), etc) used the gctl_error() routine to report errors. If they called gctl_error() they would exit with EXIT_FAILURE, otherwise they would return with EXIT_SUCCESS. If they used gctl_error() to output an informational message, for example when run with the -v (verbose) option, they would mistakenly exit with EXIT_FAILURE. A further limitation of the gctl_error() function was that it could only be called once. Messages from any additional calls to gctl_error() would be silently discarded. To resolve these problems a new function, gctl_msg() has been added. It can be called multiple times to output multiple messages. It also has an additional errno argument which should be zero if it is an informational message or an errno value (EINVAL, EBUSY, etc) if it is an error. When done the gctl_post_messages() function should be called to indicate that all messages have been posted. If any of the messages had a non-zero errno, the utility will EXIT_FAILURE. If only informational messages (with zero errno) were posted, the utility will EXIT_SUCCESS. Tested by: Peter Holm PR: 265184 MFC after: 1 week |
