ffiq
is an extension to kdb+ for loading and calling dynamic libraries using pure q
.
It is part of the Fusion for kdb+ interface collection.
The main purpose of the library is to build stable interfaces on top of external libraries, or to interact with the operating system from q
. No compiler toolchain or writing C/C++ code is required to use this library.
We are grateful to @abalkin for allowing us to adapt and expand on his original codebase.
Please report issues in this repository.
