22 When a function detects an exceptional condition at the library level,
23 it does not print an error message, or call syslog, or
31 because then you can't represent everything that an error handler
32 might need to know about an error by a single integer.
34 An exception object contains an exception code and an array
43 error handling code. Errors are reported by raising an exception.
44 When an exception is raised, we unwind the call stack
45 until we find an exception handler. If the exception is

148 Cleanup code that may raise an exception.
149 This clause is guaranteed to be executed even if an exception is
150 raised by the SM_TRY clause or by an earlier SM_FINALLY clause.
153 Exception handling code, triggered by an exception
161 An exception is an object which represents an exceptional condition,
162 which might be an error condition like "out of memory", or might be
166 raising an exception, rather than by returning an error code or
168 capable of raising an exception, its name ends in "_x".
169 (We do not raise an exception when a bug is detected in the
178 Here is an overview of some of these idioms.
182 of an exceptional condition, it reports this condition

185 Here is an example of how to construct an exception object
186 and raise an exception.
187 In this example, we convert a Unix system error into an exception.
198 When you detect an error at the application level,
200 which prints an error message on stderr and exits the program.
201 Instead, you raise an exception.
215 The latter code raises an exception, unwinding the call stack
235 names ending in _x, then it is possible that an exception will be
243 ... some code that can raise an exception ...
250 The SM_TRY ... SM_EXCEPT ... control structure handles an exception.
257 /* code that can raise an exception */
267 an exception after handling it. In the rare case that you want an
268 exception to outlive an exception handler, then you increment its
274 For example, you might want to handle an end-of-file exception
296 to describe everything that an error handler might want to know about
297 an error. And the scheme is not very extensible: if several different
302 In libsm, an exceptional condition is described
303 by an object of type SM_EXC_T.
304 An exception object is created by specifying an exception type
308 The exception arguments are an array of zero or more values.
317 An exception type is a statically initialized const object
333 one of a number of broad categories of exceptions on which an
341 This is an error that prevents the application

351 <dd>The function could not complete its task because an error occurred.

400 to an exception. The pointer value is simply copied
422 This function prints an exception of the specified type
423 onto an output stream.
431 like a bad idea to dynamically allocate an exception object to
440 a new exception object whenever you raise an exception.
441 Before you can create an exception, you need an exception type.
457 Here's an example of raising an exception:
479 in application contexts where you are raising an exception
483 later analysis by an exception handler.
506 If exception argument 3 is an int or long,
574 an unbalanced parenthesis at string offset <tt>i</tt> using:
584 An exception handler can provide special handling for regular
588 ... code that might raise an exception ...
596 External requirements may force you to define an integer code
598 an existing package that works this way. In this case, it might
600 and include the integer code as an exception argument.
603 Your package might intercept an exception E generated by a lower
609 exception E as an exception parameter, and the print function for
612 then print the subexception that is stored as an exception parameter.
620 Create a new exception. Raise an exception on heap exhaustion.
641 Increment the reference count of an exception.

723 It is legal to jump out of an SM_EXCEPT clause using goto or return;
