dyncall - A Generic Dynamic FFI package
=======================================

dyncall is a low-level toolkit providing a portable abstraction for 
handling native code dynamically at run time.
It comprises three independent components, available as C libraries, namely:

 - 'dyncall' for making function calls,
 - 'dyncallback' or writing generic callback handlers, and
 - 'dynload' for loading code.

The package provides abstractions to the Application Binary Interface 
of various hardware platforms such as x86, AMD64, ARM32/64, PowerPC32/64,
MIPS32/64 and SPARC32/64.

Our releases are thoroughly tested across all supported platforms using a
flexible test suite.

A typical application for the use of dyncall is the back-end of a FFI 
(foreign function interface) for scripting languages to connect with 
the C/C++ world.

The binary footprint of the package is approx. 10-20 kb, depending on
the platform.
Besides the test suite already mentioned, comprehensive documentation is
available.


Building the libraries
----------------------

Prequisites: 
 - C compiler such as gcc, clang, sunpro or msvc.
