// The configuration module provides a platform for reading configuration files

// a modular "configuration" object that models a hierarchical collection of

// here are designed to cover all of the basics efficiently while hiding the
// required under-cover work.

// A lot of this module is coded here in the header with the inline keyword
// because it is likely that the more basic objects can be efficiently compiled
// as inline abstractions to native calls. Really basic systems won't need
// anything beyond what is in this file.

// 20070202.1601 _M Further research has suggested that using a Semaphore in
// WIN32 environments in place of a CRITICAL_SECTION may provide the best
// performance and stability on all platforms. Specifically, SMP platforms may
// race and waste resources with CRITICAL_SECTIONs and in those cases it is
// recommended that the CRITICAL_SECTIONs may be "throttled" using Semaphores
// to limit the number of threads that may contend for a critical section. It
// is also suggested that if the Semaphore has an initialization value of 1
// the CRITICAL_SECTION is redundant. So this code has been modified to do
// precisely that!
//
// This new version also includes a ProductionGateway object that simplifies
// the producer/consumer model. The object keeps track of the number of calls
// to produce() and consume() and ensures that threads will block on consume()
// until a sufficient number of calls to produce() are made. That is, for every
// one call to produce(), a call to consume() will be allowed to proceed. The
// object also allows for the potentially asynchronous nature of these calls.

// 20070530.1751 _M Added top level exception handling in threads along with
// isRunning() and isBad() methods.

// 20060528.1647 _M All of the basics are complete and tested on both WIN32 and
// RHEL4 single and multiple processors.

// The purpose of this module is to abstract timing functions for
// cross platform C++ development usning GNU compilers in *nix and
// win32 environments (minGW). Timing resolution is in milliseconds
// throughout to provide consistency and reasonable expectations.

// 20060404 _M Added Timer::start(msclock startt) for chaining.

// 20060403 _M This "timing" module has been completed and tested on
// win32 (compiled using CodeBlocks and minGW) and on RHES3 (g++).
//
// The bottom line is that this code is perfect for most applications that
// don't need real-time interaction on the win32 platform. That is, for
// any application that can accept 15ms or so of "wiggle" in their timing
// functions. On linux I was able to observe very consistent results with
// variations measured in 1-2ms.
//
// Aynone seeking real-time accuracy on the win32 platform will need to contend
// with all of the landmines in place against that and will need to write more
// ellaborate versions of Timer::getLocalRawClock() and Sleeper::doRawSleep()
// aa appropriate for their application. The existing code should work fine for
// almost all other applications.
//
// This code was written with that in mind to some extent. That is why all of
// the timing functions are measured in milliseconds rather than microseconds
// or something smaller. Milliseconds are convenient for polling delays,
// communications timeouts, measuring database application performance, and
// other similar tasks. For that purpose - this timing module is just fine :-)

// 20060323 _M Rewrote this module from a combination of previous
// bits and pieces. This module will provide classes that abstract
// timing functions for use in GNU projects on *nix and win32 systems.
