0044 /* External API definitions */
0045
0046 /* Expat tries very hard to make the API boundary very specifically
0047    defined.  There are two macros defined to control this boundary;
0048    each of these can be defined before including this header to
0049    achieve some different behavior, but doing so is not recommended or
0050    tested frequently.
0051
0052    XMLCALL    - The calling convention to use for all calls across the
0053                 "library boundary."  This will default to cdecl, and
0054                 try really hard to tell the compiler that's what we
0055                 want.
0056
0057    XMLIMPORT  - Whatever magic is needed to note that a function is
0058                 to be imported from a dynamically loaded library
0059                 (.dll, .so, or .sl, depending on your platform).
0060
0061    The XMLCALL macro was added in Expat 1.95.7.  The only one which is
0062    expected to be directly useful in client code is XMLCALL.
0063
0064    Note that on at least some Unix versions, the Expat library must be
0065    compiled with the cdecl calling convention as the default since
0066    system headers may assume the cdecl convention.
