// useful_functions.h -- Kevin Harris (kharris@usa.net)
// Some functions which I have not been able to locate in the C++ standard
// library, and would find very useful to have.
//
// NOTE: These are declared as static, but are very small, so they won't make
// much difference to your code.
//
// Another note: The use of this header file will likely result in the compiler
// emitting warnings about one or both of these functions not being used.  This
// should be expected, and isn't much to worry about.  The only way that
// including this could have much effect on you, is if it is included in quite
// a few separately gcompiled modules (100 or more), where your executable size
// will have grown by a bit (these are REALLY small functions).
// ----------------------------------------------------------------------------
// This file is really small, and I'm not really writing much, so I'm not going
// to bother with a license.
