Change History (most recent first):
|
|
|
|
<13> 7/31/91 JL Updated Copyright. Restored Comments.
|
|
<12> 1/29/91 JL Changed parameter name of PixMap32Bit to from offscrrenPixMap to
|
|
pmHandle.
|
|
<11> 1/28/91 LN Checked in Database generate file from DSG. Grouping enums into
|
|
groups of 20.
|
|
<10> 1/25/91 stb JDR: add const on non-VAR parameters
|
|
<9> 1/15/91 KON Change useMFTempBit to UseTempMemBit. [csd]
|
|
<8> 11/28/90 JL Put formal parameter names back.
|
|
<7> 11/4/90 dba shortened inline for OffscreenVersion; use (void) instead of ();
|
|
got rid of some extraneous parameter names
|
|
<6> 10/990 JAL Changed __Safe_Link to _CPlusPlus.
|
|
<5> 9/1/90 dvb Beautify.
|
|
<4> 3/29/90 KON Put parameter size (in bytes) in high word of d0, trap selector
|
|
in low word.
|
|
<3> 3/27/90 KON Added useMFTemp flag, keepLocal flag, and prototypes for
|
|
selectors 19-23.
