Installable MathLink Programs
The Mathematica system provides a convenient way to call functions in external C and other programs. With a .tm template specifying Mathematica functions corresponding to each C function, you build a MathLink-installable binary using mprep or mcc. You can exchange not only C-like data types such as integers, reals, arrays and strings, but also arbitrary Mathematica expressions.
Install load a MathLink installable executable to call from your Mathematica session
Uninstall close down a MathLink executable, removing its Mathematica functions
LinkPatterns find functions available in a running MathLink program
., tm template file for connecting C and Mathematica functions
mprep preprocess .tm files to generate compiled C programs (Windows)
mcc complete command-line script for building MathLink programs (Unix, Mac OS X)
MLMain() special version of main() for MathLink-installable C programs
MLEvaluate(), MLEvaluateString() call back from C into Mathematica
MLPutFunction(), MLGetFunction(), ... exchange arbitrary structures
