1 dyncall - A Generic Dynamic FFI package
|
|
|
2 =======================================
|
|
|
3
|
|
|
4 dyncall is a low-level toolkit providing a portable abstraction for
|
|
|
5 handling native code dynamically at run time.
|
|
|
6 It comprises three independent components, available as C libraries, namely:
|
|
|
7
|
|
|
8 - 'dyncall' for making function calls,
|
|
|
9 - 'dyncallback' or writing generic callback handlers, and
|
|
|
10 - 'dynload' for loading code.
|
|
|
11
|
|
|
12 The package provides abstractions to the Application Binary Interface
|
|
7
|
13 of various hardware platforms such as x86, AMD64, ARM32/64, PowerPC32/64,
|
|
0
|
14 MIPS32/64 and SPARC32/64.
|
|
|
15
|
|
|
16 Our releases are thoroughly tested across all supported platforms using a
|
|
|
17 flexible test suite.
|
|
|
18
|
|
|
19 A typical application for the use of dyncall is the back-end of a FFI
|
|
|
20 (foreign function interface) for scripting languages to connect with
|
|
|
21 the C/C++ world.
|
|
|
22
|
|
|
23 The binary footprint of the package is approx. 10-20 kb, depending on
|
|
|
24 the platform.
|
|
|
25 Besides the test suite already mentioned, comprehensive documentation is
|
|
|
26 available.
