17 /* Usage Notes:
18 *
19 * this module, and the misc/win32/utf8.c modules must be
20 * compiled APR_EXPORT_STATIC and linked to an application with
21 * the /entry:wmainCRTStartup flag (which this module kindly
22 * provides to the developer who links to libaprapp-1.lib).
23 * This module becomes the true wmain entry point, and passes
24 * utf-8 reformatted argv and env arrays to the application's
25 * main() function as if nothing happened.
26 *
27 * This module is only compatible with Unicode operating systems.
28 * Mixed (Win9x backwards compatible) binaries should refer instead
29 * to the apr_startup.c module.
30 *
31 * _dbg_malloc/realloc is used in place of the usual API, in order
32 * to convince the MSVCRT that it created these entities. If we
33 * do not create them as _CRT_BLOCK entities, the crt will fault
34 * on an assert. We are not worrying about the crt's locks here,
35 * since we are single threaded [so far].
