/* USAGE:
 * 
 * Add the following include to apr_private.h for internal debugging,
 * or copy this header into apr/include add the include below to apr.h
 * for really global debugging;
 *
 *   #include "apr_dbg_win32_handles.h"
 *
 * apr_dbg_log is the crux of this function ... it uses Win32 API and
 * no apr calls itself to log all activity to a file named for the
 * executing application with a .pid suffix.  Ergo several instances
 * may be executing and logged at once.
 *
 * HANDLE apr_dbg_log(char* fn, HANDLE ha, char* fl, int ln, int nh 
 *                           [, HANDLE *hv, char *dsc...])
 *
 * returns: the handle passed in ha, which is cast back to the real return type.
 *
 * formats one line into the debug log file if nh is zero;
 * ha (hex) seq(hex) tid(hex) fn     fl         ln
 * xxxxxxxx xxxxxxxx xxxxxxxx func() sourcefile:lineno
 * The macro apr_dbg_rv makes this simple to implement for many APIs
 * that simply take args that don't interest us, and return a handle.
 *
 * formats multiple lines (nh) into the debug log file for each hv/dsc pair
 * (nh must correspond to the number of pairs);
 * hv (hex) seq(hex) tid(hex) fn   dsc  fl         ln
 * xxxxxxxx xxxxxxxx xxxxxxxx func(arg) sourcefile:lineno
 * In this later usage, hv is the still the return value but is not
 * treated as a handle.
