The format of the GetExceptionInfo method is: GetExceptionInfo ( ExceptionInfo *exception ); A description of each parameter follows: exception: The exception info. ## GetLocaleExceptionMessage GetLocaleExceptionMessage() converts a enumerated exception severity and tag to a message in the current locale. The format of the GetLocaleExceptionMessage method is: const char *GetLocaleExceptionMessage ( const ExceptionType severity, const char *tag ); A description of each parameter follows: severity: the severity of the exception. tag: the message tag. ## MagickError MagickError() calls the error handler methods with an error reason. The format of the MagickError method is: void MagickError ( const ExceptionType error, const char *reason, const char *description ); A description of each parameter follows: exception: Specifies the numeric error category. reason: Specifies the reason to display before terminating the program. description: Specifies any description to the reason. `MagickFatalError()` calls the fatal error handler methods with an error reason. The format of the MagickError method is:
        void MagickFatalError(const ExceptionType error,const char *reason,
          const char *description)
A description of each parameter follows: exception: Specifies the numeric error category. reason: Specifies the reason to display before terminating the program. description: Specifies any description to the reason. ## MagickWarning MagickWarning() calls the warning handler methods with a warning reason. The format of the MagickWarning method is: void MagickWarning ( const ExceptionType warning, const char *reason, const char *description ); A description of each parameter follows: warning: The warning severity. reason: Define the reason for the warning. description: Describe the warning. ## SetErrorHandler SetErrorHandler() sets the error handler to the specified method and returns the previous error handler. The format of the SetErrorHandler method is: ErrorHandler SetErrorHandler ( ErrorHandler handler ); A description of each parameter follows: handler: The method to handle errors. ## SetExceptionInfo SetExceptionInfo() set the exception severity. The format of the SetExceptionInfo method is: unsigned int SetExceptionInfo ( ExceptionInfo *exception, ExceptionType severity ); A description of each parameter follows: exception: The exception info. severity: The exception severity. ## SetFatalErrorHandler SetFatalErrorHandler() sets the fatal error handler to the specified method and returns the previous fatal error handler. The format of the SetErrorHandler method is:
        ErrorHandler SetErrorHandler(ErrorHandler handler)
A description of each parameter follows: handler: The method to handle errors. ## SetWarningHandler SetWarningHandler() sets the warning handler to the specified method and returns the previous warning handler. The format of the SetWarningHandler method is: ErrorHandler SetWarningHandler ( ErrorHandler handler ); A description of each parameter follows: handler: The method to handle warnings. ## ThrowException ( void ) ThrowException() throws an exception with the specified severity code, reason, and optional description. The format of the ThrowException method is: unsigned int ( void ) ThrowException ( ExceptionInfo *exception, const ExceptionType severity, const char *reason, const char *description ); A description of each parameter follows: exception: The exception. severity: The severity of the exception. reason: The reason of the exception. description: The exception description.
