svn commit: r170461 - /apr/apr/trunk/misc/win32/rand.c

[wr...@apache.org]

Author: wrowe
Date: Mon May 16 14:40:28 2005
New Revision: 170461

URL: http://svn.apache.org/viewcvs?rev=170461&view=rev
Log:

  Presume when we grab random data, 2^31 bytes is quite alot.

  If this solution isn't sufficient (thus: the XXX comment),
  we will need a loop where sizeof(apr_size_t) > sizeof(DWORD)
