most likely this is the version your application w ill call. In this example, this

form of the i nitialization function is called

libtriangleInitialize.

bool libtriangleInitia lize (void)

This function creates an MCR instance using the default print and error

handlers, and other information generated d uring the compilation process.

However, if you want more control over ho w printed output and error

messages are handled, yo u may call the second form of the function, which

takes two arguments.

bool libtriangleInitia lize WithHandlers(

mclOutputHandlerFcn error_handler,

mclOutputHandlerFcn print_handler

)

By calling this function, you can provide your own versions of the print

and error h an d ling routines called by the MCR. Each of these routines has

the same signature (for complete details, see “Print and Error Handling

Functions” on page 7-27). By overriding the defaults, you can control how

output is displayed and, for example, whether or not it goes into a log file.

Note Before calling either form of the library initialization routine, you must

first call

mclInitializeApplication to set u p the global MCR state. See

“Calling a Shared L ibrary” on page 7-11 for more information.

On Microsoft Windows platforms, MATLAB C ompiler generates an additional

initialization function, the standard Microsoft DLL i nitialization function

DllMain.

BOOL WINAPI DllMain(HINSTANCE hInstance, DWORD dwReason,

void *pv)

The g enerated DllMain performs a very important service; it lo cates the

directory in which the shared library is stored on disk. This information is

used to find the C TF archive, without w hich the application will not run. If
