7 Libraries

Using C/C++ Shared Libraries on Mac OS X

To use a MATLAB Compiler generated library on Mac O S X, you must create

a separat e thread tha t initializes th e shared library and call that library’s

functions. The main thread of your application must create and execute a

CFRunLoop. The main thread of the application is the thread that calls your

driver program’s

main() function. The body of your main () function must do

two things:

• Create a new thread, passing to it the address of a thread-function

containing the library initialization and necessary calls to the shared

library g enerated by MATLAB Compiler.

• Initialize and start a

CFRunLoop by calling CFR unLoopRun().

The new thread does the main work of the application, including calling

MATLAB Compiler generated libraries, while the main thread is devoted

to the

CFRunLoop.

Note You must be familiar w ith the Mac OS X CFRunLoop object. Consult the

Mac OS X Core Foundation Reference for a detailed discussion on run l oops

and event-driven programming on Mac OS X.

The following ex ample illustrates this procedure. This e xample rewrites the

C shared library example from this chapter for use on Mac OS X. Follow the

same procedure as in the earlier exam ple to build and run this application.
