No. Well let me qualify.  There is a libgdb, but I have never used it
and I am not sure anyone has for some many years.  I am not sure how
maintained it is either. Someone else might know more.

A direct C API, aka what we have with Python, while nice, is not
likely any time soon.  We cannot just expose all of the innards of GDB
automatically, say with some script, to a C API.  GDB internals were
never designed to be exposed in such a way.  The API would have to be
a curated API and I don't see anyone working on that goal at present.

If you are determined to go the C route, IMO your best bet would be to
modify GDB directly to your needs and rebuild.  GDB is fairly trivial
to build.  Less so to modify, but those are your options at the
moment. ;)

As it is, for scripting with have Python and Guile based scripting.
