Sharing external function libraries
If you have written external functions whose source code can
be compiled on all target platforms, you can simplify the external
function declarations in PowerBuilder if you give the function library
a name that works on all platforms.
The lowest common denominator for names is the DOS 8+3
format. On Windows and UNIX, you can change the name of the dynamic
library or shared object file at any time.
For more information about calling external
functions on Windows and UNIX, see Chapter 20, “Using External Functions
and Other Processing Extensions”.
For information about data types for external
function arguments, see the PowerScript Reference
