Macros
#define	MUTILS_DELETE(PTR)   do { if((PTR)) { delete (PTR); (PTR) = NULL; } } while(0)
	Deletes the object, if and only if the given pointer is not NULL. Also sets pointer to NULL after object has been deleted.
#define	MUTILS_DELETE_ARRAY(PTR)   do { if((PTR)) { delete [] (PTR); (PTR) = NULL; } } while(0)
	Deletes the array, if and only if the given pointer is not NULL. Also sets pointer to NULL after array has been deleted.
#define	MUTILS_ZERO_MEMORY(PTR)   memset(&(PTR), 0, sizeof((PTR)))
	Clears the specified variable or struct by setting all of its bytes to zero (0x00). Do not use for arrays.
#define	MUTILS_WCHR(STR)   (reinterpret_cast<const wchar_t*>((STR).utf16()))
	Converts a given QString object to a wchar_t* pointer. Does not copy the string data, so do not free the pointer! The returned pointer only remains valid until the underlying QString is modified or goes out of scope.
#define	MUTILS_UTF8(STR)   ((STR).toUtf8().constData())
	Converts a given QString object to a char* pointer. The string is converted to UTF-8 encoding. The pointer is valid only while the expression is being evaluated, so do not free or store this pointer! Mainly useful for function calls that require a char* argument.
#define	MUTILS_QSTR(STR)   (QString::fromUtf16(reinterpret_cast<const unsigned short*>((STR))))
	Creates a QString object from a given wchar_t* buffer. The buffer is expected to conatin a NULL-terminated string in UTF-16 encoding. The string data is copied into the new QString object, however the original buffer will not be freed automatically!
#define	MUTILS_BOOL2STR(X)   ((X) ? "1" : "0")
	Converts a boolean expression into a string. A true boolean expression is converted to the string "1"; a false boolean expression is converted to the string "0".
