[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index] [Xen-devel] [PATCH v3-RESEND 06/28] libxc: ocaml: add simple binding for xentoollog (output only).
These bindings allow ocaml code to receive log message via xentoollog
but do not support injecting messages into xentoollog from ocaml.
Receiving log messages from libx{c,l} and forwarding them to ocaml is
the use case which is needed by the following patches.
Add a simple noddy test case (tools/ocaml/test).
Signed-off-by: Ian Campbell <ian.campbell@xxxxxxxxxx>
Signed-off-by: Rob Hoes <rob.hoes@xxxxxxxxxx>
---
New in v3:
* Auto-generate the log-level converters from xentoollog.h.
* Move the stdio logger from the library to the test suite.
* Use a counter instead of a random number when registering a callback.
