// 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).")
