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;
30 * #include "apr_dbg_win32_handles.h"
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.
37 * HANDLE apr_dbg_log(char* fn, HANDLE ha, char* fl, int ln, int nh
38 * [, HANDLE *hv, char *dsc...])
40 * returns: the handle passed in ha, which is cast back to the real return type.
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.
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.
