From 81bb6873f1c0291fecbf6e429ad15ac3db66a4c0 Mon Sep 17 00:00:00 2001 From: Aki Date: Tue, 12 Mar 2024 22:07:03 +0100 Subject: Legal notices updated Rename contrib -> third-party intendes to express the origin and purpose of that part of the code better. I plan to readd contrib/ again but with more in-project things like bash-completions, dev workflow scripts etc. --- third-party/Opcode/Ice/IceRandom.h | 42 ++++++++++++++++++++++++++++++++++++++ 1 file changed, 42 insertions(+) create mode 100644 third-party/Opcode/Ice/IceRandom.h (limited to 'third-party/Opcode/Ice/IceRandom.h') diff --git a/third-party/Opcode/Ice/IceRandom.h b/third-party/Opcode/Ice/IceRandom.h new file mode 100644 index 0000000..3170b33 --- /dev/null +++ b/third-party/Opcode/Ice/IceRandom.h @@ -0,0 +1,42 @@ +/////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////// +/** + * Contains code for random generators. + * \file IceRandom.h + * \author Pierre Terdiman + * \date August, 9, 2001 + */ +/////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////// + +/////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////// +// Include Guard +#ifndef __ICERANDOM_H__ +#define __ICERANDOM_H__ + + FUNCTION ICECORE_API void SRand(udword seed); + FUNCTION ICECORE_API udword Rand(); + + //!
