Hi folks,
Since I needed a way to call arbitrary C functions dynamically (while
knowing their pointer + signature), I decided to write a binding to
libffi for D.
https://github.com/lycus/libffi-d
There is heavy focus on simplicity: It is composed of 3 enums (FFIType,
FFIStatus, FFIInterface), one alias (FFIFunction), and one function
(ffiCall). The API is fairly self-describing, so I haven't really spent
a whole lot of time on docs. For examples, see the tests sub-directory
(please also read 'info libffi').
Known limitations:
* No access to the closure API.
* No access to the 'raw' API (which is undocumented in libffi anyway).
Known issues:
* Detection of soft float ABIs is not currently done (due to limitations
in most D compilers).
* ABI overriding for some rare Unix ABIs is not currently possible.
* Currently no good way to actually use the library on Windows. Anyone
who knows their stuff about DMD and DLLs on Windows, please do
contribute. ;)
If you run into any issues, please throw a test case at the GitHub issue
tracker and I'll look into it. Enjoy!
