 * The basic debugging tool is the OSPM_DBG macro. Although not
 * normally directly accessible by the main SDK code, it is the
 * foundation on which all other debugging tools are built. If
 * OSPC_DEBUG is not defined, then the macro has no effect. If it
 * is defined, though, the macro checks a condition and, if the
 * condition is true, executes a printf-like function. The
 * actual function called is OSPM_DBGPRINTF, which can be re-
 * defined to be a special debugging printf function if
 * appropriate for the environment. For now, it's just defined
 * to be printf.
 */

/*
 * The OSPM_DBG macro is slightly tricky since printf takes
 * a variable number of arguments. Notice that there is no
 * parentheses around the params parameter when it's used
 * in the macro. Those parentheses must be supplied when
 * the macro is invoked in the code. The following example
 * shows how the macro might be used:
 *
 *      OSPM_DBG(cond,("debugging %u %u %u\n",1,2,3));
 *
 * Notice the extra parentheses around the parameters that
 * follow the first.

 * At last, here are the real debug macros. They are intended

 * to memory management. When memory allocation problems need
 * to be debugged, OSPVDbgFlag should be set so that the
 * OSPC_DBGMEM bit is set. For the same reasons given in the
 * description of OSPM_DBG, whenever these macros are used in
 * the code, two sets of parentheses must be used. For example:
 *
 *    OSPM_DBGMEM(("allocating %u bytes of memory\n", size));

 * Finally, a special debugging macro just for error logging.
 * The macro takes two parameters: an error code and descriptive

 *
 * OSPM_DBGERRORLOG(OSPC_ERR_COMM_ALLOC_FAIL, "memory allocation failed");
 *
 * The resulting print line will include the code and text, as
 * well as the file name and line number from which the macro was
 * invoked (as in assert). For example:
 *
 *     ERROR 0001: memory allocation failed
 *           File: ospcomm.c  line 178
