But an awful lot of the providers for pegasus are written in C.But we're concerned with only one, the virt provider. None of the others will use libqemu?The point is, C is a lowest common denominator and it's important to support in a proper way.Problem is, it means horrible support for everyone else.
Why?We can provide a generic QMP dispatch interface that high level languages can use. Then they can do fancy dispatch, treat QErrors as exceptions, etc.
We just ought to also provide some simple C wrappers for all of the functions. Yes, the C interface is inferior to the generic interface but that's fine.
