Improved Foreign Function Interface and Dynamic Bindings to C Libraries R package rdyncall version 0.10.2 Provides a cross-platform framework for dynamic binding of C libraries using a flexible Foreign Function Interface (FFI). The FFI supports almost all fundamental C types, multiple calling conventions, symbolic access to foreign C struct/union data types and wrapping of R functions as C callback function pointers. Dynamic bindings to shared C libraries are data-driven by cross-platform binding specifications using a compact plain text format; the package includes a 'DynPort' binding specification for 'SDL3' generated from current headers with 'porter'. The package includes a variety of technology demos and OS-specific notes for installation of shared libraries. For the underlying methods and bundled 'DynCall' libraries, see Adler (2012) <doi:10.32614/RJ-2012-004> and Adler and Philipp (2008) <https://dyncall.org>.
