/** @file
 * This file contains macros which are convenient to use for 
 * sprinkling error checking around liberally in SimTK programs, a
 * practice which is highly encouraged. You can think of this as
 * a generalization of the standard assert() macro. By default, 
 * these macros evaporate completely in a release build, but are
 * present in any debug build. Macros are also provided which are
 * always present in cases where the error checking is not a 
 * performance problem, and those should be used in preference
 * to the disappearing ones when appropriate. Also, you can force
 * the disappearing macros to remain present on a file-by-file basis,
 * primarily for use in debugging those annoying problems which only
 * occur in release builds and won't reproduce in a debug build.
 *
 * Most macros have a similar structure, something like this:
 * <pre>
 *    SimTK_MACRONAME[nargs][_ALWAYS](cond, printfString [, args...])
 * for example
 *    SimTK_ASSERT3(lower<count && count<upper,
 *                  "expected %d < count < %d but count=%d",
 *                  lower, upper, count);
 * or
 *    SimTK_ASSERT3_ALWAYS(lower<count && count<upper,
 *                  "expected %d < count < %d but count=%d",
 *                  lower, upper, count);
 * </pre>
 * To override the disappearance of the non-ALWAYS macros, your 
 * compilation should define a preprocessor symbols like
 * SimTK_KEEP_ASSERT, SimTK_KEEP_ERRCHK, etc.
 *
 * These macros will also capture the current file name and line 
 * number for reporting to developers when appropriate, and those
 * with a condition that failed will include the condition in the 
 * message.
 *
 * Note that these are *global* symbols, so we use the reserved
 * SimTK_ name prefix (since we can't use the SimTK:: namespace 
 * for macros) to attempt to avoid pollution of user programs.
 *
 * We distinguish between macros which are used as internal 
 * "bugcatchers" and those which are used to report errors to
 * API users. The C++ exception mechanism is used in both circumstances
 * but the meaning and intended audience is quite different. Any
 * macro with 'ASSERT' in the name represents an internal error
 * which cannot be attributed to user misbehavior. Other macros
 * are for communicating with users. Those need to be carefully documented
 * so that users can selectively catch the exceptions when appropriate.

// --------------------------------- RANGECHECK --------------------------------
// These exceptions are to be used for situations in which a user of a SimTK
// API method screws up by providing bad indices or dimensions. These are special
// cases of the more general APIARGCHECK macros, providing "canned" error messages
// for several common situations. Although there are several different macro 
// names here, all are controlled by SimTK_KEEP_RANGECHECK to allow enabling of
// these index- and size-validating tests together in Release mode.
//
//   INDEXCHECK: Note that we allow the index to be equal to the lower
//     bound (zero) but it must be strictly less than the upper bound.
//   SIZECHECK: A size or size expression must be >= 0 and less than OR EQUAL
//     to the maximum size.
//   SIZECHECK_NONNEG: A size argument must be >= 0.
//   VALUECHECK: A floating point is required to be within a certain range.
//   VALUECHECK_NONNEG: A floating point argument must be non-negative.
