/* Usage Notes:
|
|
*
|
|
* this module, and the misc/win32/utf8.c modules must be
|
|
* compiled APR_EXPORT_STATIC and linked to an application with
|
|
* the /entry:wmainCRTStartup flag. This module becomes the true
|
|
* wmain entry point, and passes utf-8 reformatted argv and env
|
|
* arrays to the application's main function.
|
|
*
|
|
* This module is only compatible with Unicode-only executables.
|
|
* Mixed (Win9x backwards compatible) binaries should refer instead
|
|
* to the apr_startup.c module.
|
|
*
|
|
* _dbg_malloc/realloc is used in place of the usual API, in order
|
|
* to convince the MSVCRT that they created these entities. If we
|
|
* do not create them as _CRT_BLOCK entities, the crt will fault
|
|
* on an assert. We are not worrying about the crt's locks here,
|
|
* since we are single threaded [so far].
