31 Change History (most recent first):
32
33 <2> 2/7/01 JL [2500429] Changed null output parameters to real variables when
34 calling GetSharedLibrary to prevent crashes with older versions
35 of CFM. Added standard header. Updated names of includes. Added
36 C function implementations of accessors that used to be macros
37 since the generated Pascal headers no longer contain
38 implementations. Updated various other routines to use new
39 calling convention of the accessor functions.
40 <1> 12/06/99 JL MoreFiles 1.5.
