Macro definitions for void pointers to make the API readable.
Defines a C-Application Programming Interface (API) to the ML, see also mlUtilsAPI.h. It supplies control to most parts of the ML and much higher binary compatibility than the C++ binary interface. It also can be used to link the ML to other programming languages. All functions of this interface are highly (however not completely) protected with exception handlers and tested to guarantee high security when using this functions. All detected errors will be handled by the ErrorOutput class if not explicitly returned by returned error codes. Disable all c++ specific things in mlInitSystemML for this C-API. Include ML library initialization code and system dependencies. Undefine macro to avoid macro space pollution. Include all non ML includes which shall be available generally. Include ML version information.
#define	mlField void
	A macro name for a void pointer to a field in the ML to make pointer more readable.

#define	mlSensor void
	A macro name for a void pointer to a sensor in the ML to make pointer more readable.

Returns ML_RESULT_OK in case of successful library load or an error code describing the error (e.g., ML_LIBRARY_LOAD_ERROR if the library is not found or not linked).

As a side effect the most recently loaded library name is updated to the library name (see Runtime::setRecentlyLoadedDllName for more infos) and the initialization of the loaded library is called implicitly. Errors are posted only on invalid parameters, crashes on library initialization, but NOT if the library is not found or not loadable. So this library can be used to check for a library and to handle unloadable libraries without errors. If libHandle is passed as NULL pointer then it is ignored; otherwise *libHandle is set to the return value of the library load function. It will be needed to unload the library with MLUnLoadLibrary.

Returns pointer to a null terminated string containing the name of the class represented by type.

type must be a non-NULL pointer to a valid mlRuntimeType object. Otherwise a ML_BAD_PARAMETER error will occur and NULL is returned.

◆ MLTypeGetParentName()

MLEXPORT const char * MLTypeGetParentName ( mlType * type )

Returns pointer to a null terminated string containing the name of the parent class of that represented by type.

A pointer to "No parent" is returned if there is no such class. type must be a non-NULL pointer to a valid mlRuntimeType object. Otherwise a ML_BAD_PARAMETER error will occur and NULL is returned.

◆ MLTypeGetParentType()

MLEXPORT mlType * MLTypeGetParentType ( mlType * type )

Returns pointer to the RuntimeType instance representing the type of the parent class of that represented by type.

A NULL pointer is returned if there is no such class. type must be a non-NULL pointer to a valid RuntimeType object. Otherwise a ML_BAD_PARAMETER error will occur and NULL is returned.

◆ MLTypeIsAbstract()

MLEXPORT MLint32 MLTypeIsAbstract ( mlType * type )

Returns true (== 1) if type is abstract, otherwise 0 (=false).

type must be a non-NULL pointer to a valid mlRuntimeType object. Otherwise a ML_BAD_PARAMETER error will occur. -1 is return value after such or fatal errors.

◆ MLTypeIsDerivedFrom()

MLEXPORT MLint32 MLTypeIsDerivedFrom	(	mlType *	type,
		const char *	parent )

Returns true (== 1) if runtime type type is derived from the parent class with the name given by parent.

The return value is false (== 0) if not or on errors or if any of type or parent is NULL (which is legal to pass to the call). The non-NULL type must be a pointer to a valid RuntimeType object and parent a pointer to a null terminated string containing the name of the parent class.

◆ MLUnLoadLibrary()

MLEXPORT MLErrorCode MLUnLoadLibrary	(	const char *	name,
		MLLibraryHandle	libHandle,
		char **	errStr )

Unloads the given shared library.

name must be a non-NULL pointer to a non-empty null terminated string. Otherwise a fatal error will occur. Returns ML_RESULT_OK in case of successful library unload or an error code describing the error.

Note: MeVisLab uses its own library unloading and will not call this function.

The libHandle parameter must be the corresponding library handle created by MLLoadLibraryWOErrorExt for successful operation. The responsibility for safe removal of the library is completely up to the application - the ML cannot check completely whether - for example - other libraries depend on the unloaded one. If errStr is passed as a non-NULL pointer then it is set to a string describing the error. *errStr must always be freed with MLFree(). Note that detection of references is limited to ML type; it does not cover all possible link references etc.

Note that library unloading has a number of side effects:

All runtime types registered in the runtime type system are removed;
The library is not removed if other libraries still use it.
If instances of classes of the library exist the library can be unloaded; however those libraries will not operate safely any more. It is possible to load new code for that library again; whether the already existing instances will operate safely again depends on the content of the reloaded library. This behavior should not be considered reliable.
Opened resources not closed properly by the library programmer may remain open (for example type registrations in other type systems than the one of the ML, initialized device drivers etc.). Thus use this function only with extreme care.
