/* File: FragLoad.h Contains: CFM Public API Written by: Erik Eidt, Alan Lillich, Jeff Cobb Copyright: © 1993 by Apple Computer, Inc., all rights reserved. Change History (most recent first): <15> 6/16/93 ELE (with AWL) Added new error code for UserInitProcFailure. <14> 6/9/93 jrc (with SP) In the CFMTrap macro, remove the cast of (arg) to signed short. This was confusing the interfacer. <13> 6/9/93 EPT Changes for Universal Headers. Synched up with Reality. <12> 6/5/93 BT (With JRG) "#ifndef interface_glue" should only be bracketing the prototypes, not the type information. This was causing a problem for ProcessesPriv.h where Eric was expecting some type information to be available. <11> 5/10/93 jrc Make C++ Happy. <10> 4/7/93 jrc Use symbolic names for the MixedMode and CFM A-traps. <9> 3/17/93 JRG Change how procinfos are constructed <8> 3/4/93 AWL Change to "pascal" routines for Dagon. <7> 3/2/93 jrc Fix Erik's fixes. "FourBytes" not "FourByte". <6> 3/2/93 ELE Fixed two typo's in proc infos. <5> 2/18/93 ELE Moved a bunch of stuff into here from CodeFragments.h <4> 2/15/93 ELE Added kAnyArchType. <3> 1/28/93 jrc Rev for d4 MixedMode. */ /******************************************************************************* FILENAME FragLoad.h COPYRIGHT Copyright © Apple Computer, Inc. 1992 All rights reserved. *******************************************************************************/ #ifndef __FRAGLOAD__ #define __FRAGLOAD__ 1 #include #include #include typedef long ConnectionID;
