[fireball] 34995: Gregor Schneider <[e-mail]> - Return error code "buffer overflow" instead of "buffer too small" and only do that if really necessary - Only append 0 if Length parameter allows to do so - Use uppercase letters Aleksey Bragin <[e-mail]> - Wrap it into PSEH, however commented out till a solution for the bootloader is found (linking freeldr with PSEH is not very beautiful). See issue #3583 for more details.

- Use uppercase letters

Aleksey Bragin <aleksey(a)reactos.org>
- Wrap it into PSEH, however commented out till a solution for the bootloader is found
(linking freeldr with PSEH is not very beautiful).
