    The general rule is that new public functions should have a clearly public name, and should be documented. So if it is not documented, it is not public (at least not yet if it is new), and should be avoided because it is liable to change.

    Thank you for the clear explanation, Andrew.

    Ironically, I found a private function for determining whether something is public:

    (In IC616-ISR5): 

    _iliIsPublicFunc 'artUnique => nil
_iliIsPublicFunc 'car => t
_iliIsPublicFunc 'getShellArgs => nil
_iliIsPublicFunc 'push => nil
_iliIsPublicFunc 'pop => nil
_iliIsPublicFunc 'techSetTechFileName => nil

     

    
It is curious that techGetTechFileName() is public, but techSetTechFileName() isn't in IC616—
    
especially since it was public in IC5141!

"@(#)$CDS: icfb.exe version 5.1.0 03/30/2009 07:18 (cicln04) $"
> help techSetTechFileName
Consulting cdsFinder database (may take a while) ...
 
techSetTechFileName( 
g_ID
t_techfileName 
) 
=> t | nil
 
Updates the techFile property of the specified library or cellview.
This property is one of two that attach a library or cellview
to a technology file.
