// Function throwErrnoExc() throws an exception which corresponds to
// error code errnum. The exception text is initialized with a copy
// of the string passed to throwErrnoExc(), where all occurrences of
// "%T" have been replaced with the output of strerror(oserror()).
//
// Example:
//
2012-08-25 04:31:49 +08:00
// If opening file /tmp/output failed with an ENOENT error code,
// calling
//
// throwErrnoExc ();
//
// or
//
// throwErrnoExc ("%T.");
//
// will throw an EnoentExc whose text reads
//
// No such file or directory.
//
// More detailed messages can be assembled using stringstreams:
//
// std::stringstream s;
// s << "Cannot open file " << name << " (%T).";
// throwErrnoExc (s);
//
// The resulting exception contains the following text:
//
// Cannot open file /tmp/output (No such file or directory).
//
// Alternatively, you may want to use the THROW_ERRNO macro defined
// in IexMacros.h:
//
// THROW_ERRNO ("Cannot open file " << name << " (%T).")
//
