Wolfram Language & System 11.0 (2016)|Legacy Documentation
Wolfram LibraryLink provides a powerful way to connect external code to the Wolfram Language, enabling high-speed and memory-efficient execution. It does this by allowing dynamic libraries to be directly loaded into the Wolfram Language kernel so that functions in the libraries can be immediately called from the Wolfram Language. Wolfram LibraryLink allows exchanging arbitrary data with the linked library: integers, reals, packed arrays, strings, and arbitrary Wolfram Language expressions, as well as sending messages and calling back to the Wolfram Language.
LibraryFunctionLoad — load a function from a dynamic library into the Wolfram Language
LibraryFunction — a function that calls into a dynamic library
LibraryFunctionInformation — information on a library function
LibraryLoad — load a library without calling any functions
ConnectLibraryCallbackFunction — connect a Wolfram Language function for callback from a library
CreateManagedLibraryExpression — manage library memory through an expression
