I am in favor of such an option on the condition that it is
temporary. In other words, only until we decide "we have converted
enough code to use this code so we should remove the option now." The
reason is that otherwise, we will be faced with numerous "#ifdef
LIBMBUF ... #else ... #endif" code. I assume this is what you meant,
anyway, so I have no objections. :-) The API looks great by the way,
and I will try to give a more detailed review in the next few days.
:-)
For now:
#define M_TRYWAIT M_WAIT is not right.
(M_WAIT is no longer to be used in the mbuf code.)
The succesfull return values are 0, I don't have a problem with this,
specifically, but I would assume that this:
if (!mb_init(mbp)) ... would be more "logical" (I use the term
loosely) if it meant: "if initialization fails" (now it means "if
initialization is succesful").

Hmmm. Maybe subr_mblib.c and libmb.h ? I don't want to turn this
into a bikeshed ( :-) ), so I suggest that you decide. Personally, I
would prefer that it be something other than "subr_mbuf.c" simply
because it may be a little misleading in some cases.

Boris, this is really a great interface and nice looking, clean code.
Thank you!
