.TP
LC_CBRET_OKAY
Returning LC_CBRET_OKAY from a callback indicates that all went well and further processing may continue.
.TP
LC_CBRET_ERROR
Returnning LC_CBRET_ERROR from a callback indicates that the command failed for some reason, the error will be passed back down the chain back to the
.BR lc_process (3)
call that began processing the configuration data.  If LC_CBRET_ERROR is returned from a callback that begins a section, the entire section is ignored.


.SH "RETURN VALUE"
On success 0 is returned, otherwise -1 is returned.
