00053 // Function throwErrnoExc() throws an exception which corresponds to
00054 // error code errnum.  The exception text is initialized with a copy
00055 // of the string passed to throwErrnoExc(), where all occurrences of
00056 // "%T" have been replaced with the output of strerror(oserror()).
00057 //
00058 // Example:
00059 //   
00060 // If opening file /tmp/output failed with an ENOENT error code,
00061 // calling
00062 //
00063 //      throwErrnoExc ();
00064 //
00065 // or
00066 //
00067 //      throwErrnoExc ("%T.");
00068 //
00069 // will throw an EnoentExc whose text reads
00070 //
00071 //      No such file or directory.
00072 //
00073 // More detailed messages can be assembled using stringstreams:
00074 //
00075 //      std::stringstream s;
00076 //      s << "Cannot open file " << name << " (%T).";
00077 //      throwErrnoExc (s);
00078 //
00079 // The resulting exception contains the following text:
00080 //
00081 //      Cannot open file /tmp/output (No such file or directory).
00082 //
00083 // Alternatively, you may want to use the THROW_ERRNO macro defined
00084 // in IexMacros.h:
00085 //
00086 //      THROW_ERRNO ("Cannot open file " << name << " (%T).")
