/* When running as a subdaemon controlled by lightningd the hsmd will
|
|
* report logging, debugging information and crash reports to
|
|
* lightningd via the status socket, using the wire protocol used in
|
|
* LN more generally. This is done so lightningd can print add the
|
|
* messages to its own logs, presenting a unified view of what is
|
|
* happening.
|
|
*
|
|
* When using libhsmd not as a subdaemon controlled by lightningd we
|
|
* cannot make use of the communication primitives we used in that
|
|
* context. For this reason libhsmd defers the selection of actual
|
|
* primitives to link time, and here we provide simple ones that just
|
|
* print to stdout, as alternatives to the status wire protocol ones.
