24 /* USAGE:
25  *
26  * Add the following include to apr_private.h for internal debugging,
27  * or copy this header into apr/include add the include below to apr.h
28  * for really global debugging;
29  *
30  * #include "apr_dbg_win32_handles.h"
31  *
32  * apr_dbg_log is the crux of this function ... it uses Win32 API and
33  * no apr calls itself to log all activity to a file named for the
34  * executing application with a .pid suffix. Ergo several instances
35  * may be executing and logged at once.
36  *
37  * HANDLE apr_dbg_log(char* fn, HANDLE ha, char* fl, int ln, int nh
38  * [, HANDLE *hv, char *dsc...])
39  *
40  * returns: the handle passed in ha, which is cast back to the real return type.
41  *
42  * formats one line into the debug log file if nh is zero;
43  * ha (hex) seq(hex) tid(hex) fn fl ln
44  * xxxxxxxx xxxxxxxx xxxxxxxx func() sourcefile:lineno
45  * The macro apr_dbg_rv makes this simple to implement for many APIs
46  * that simply take args that don't interest us, and return a handle.
47  *
48  * formats multiple lines (nh) into the debug log file for each hv/dsc pair
49  * (nh must correspond to the number of pairs);
50  * hv (hex) seq(hex) tid(hex) fn dsc fl ln
51  * xxxxxxxx xxxxxxxx xxxxxxxx func(arg) sourcefile:lineno
52  * In this later usage, hv is the still the return value but is not
53  * treated as a handle.
