  13
  14 This library provides language independent support for raising scripting
  15 language exceptions in SWIG generated wrapper code.    Normally, this is
  16 used in conjunction with the %except directive.
  17
  18 To raise an exception, use the following function call :
  19
  20        SWIG_exception(int exctype, char *msg);
  21
  22 'exctype' is an exception type code and may be one of the following :
  23
  24        SWIG_MemoryError
  25        SWIG_IOError
  26        SWIG_RuntimeError
  27        SWIG_IndexError
  28        SWIG_TypeError
  29        SWIG_DivisionByZero
  30        SWIG_OverflowError
  31        SWIG_SyntaxError
  32        SWIG_ValueError
  33        SWIG_SystemError
  34        SWIG_UnknownError
  35
  36 'msg' is an error string that should be reported to the user.
  37
  38 The library is normally used in conjunction with the %except directive
  39 as follows :
  40
  41 %except {
  42        try {
  43           $function
  44        } catch RangeError {
  45           SWIG_exception(SWIG_IndexError,"Array index out of bounds");
  46        } catch(...) {
  47           SWIG_exception(SWIG_UnknownError,"Uncaught exception");
  48        }
  49 }
  50
  51 It is important to note that the SWIG_exception() function is only available
  52 to the C code generated by SWIG.  It is not available in the scripting language
  53 interface itself.
