/* Error handling
|
|
* This package defines a set of macros that allows code to raise and
|
|
* handle exceptions.A macro is provided which signals an error, which
|
|
* does a non - local goto to the innermost enclosing exception handler.
|
|
* A set of macros sets up exception handling code.
|
|
*
|
|
* To catch exceptions that occur inside a block of code(i.e., in the
|
|
* code or in any subroutines called by the code), begin the block with
|
|
* ERRBEGIN.At the end of the protected code, place the exception
|
|
* handler, which starts with ERRCATCH.At the end of the exception
|
|
* handler, place ERREND.If no exception occurs, execution goes
|
|
* through the protected code, then resumes at the code following
|
|
* the ERREND.
|
|
*
|
|
* The exception handler can signal another error, which will cause
|
|
* the next enclosing frame to catch the error.Alternatively, if
|
|
* the exception handler doesn't signal an error or return, execution
|
|
* continues at the code following the ERREND.Exceptions that are
|
|
* signalled during exception handling will be caught by the next
|
|
* enclosing frame, unless the exception handler code is itself
|
|
* protected by another ERRBEGIN - ERREND block.
|
|
*
|
|
* To signal an error, use errsig().
|
|
*
|
|
* To use a string argument in a signalled error, cover the string
|
|
* with errstr(ctx, str, len); for example:
|
|
*
|
|
* errsig1(ctx, ERR_XYZ, ERRTSTR, errstr(ctx, buf, strlen(buf)));
|
|
*
|
|
* This copies the string into a buffer that is unaffected by
|
|
* stack resetting during error signalling.
