/**
* \brief
* Creates a new ANTLR3 exception structure
*
* \param[in] exception
* One of the ANTLR3_xxx_EXCEPTION indicators such as #ANTLR3_RECOGNITION_EXCEPTION
*
* \param[in] message
* Pointer to message string
*
* \param[in] freeMessage
* Set to ANTLR3_TRUE if the message parameter should be freed by a call to
* ANTLR3_FREE() when the exception is destroyed.
*
* \returns
* Pointer to newly initialized exception structure, or an ANTLR3_ERR_xx defined value
* upon failure.
*
* An exception is 'thrown' by a recognizer when input is seen that is not predicted by
* the grammar productions or when some other error condition occurs. In C we do not have
* the luxury of try and catch blocks, so exceptions are added in the order they occur to
* a list in the baserecognizer structure. The last one to be thrown is inserted at the head of
* the list and the one currently installed is pointed to by the newly installed exception.
*
* \remarks
* After an exception is created, you may add a pointer to your own structure and a pointer
* to a function to free this structure when the exception is destroyed.
*
* \see
* ANTLR3_EXCEPTION
