| 11 | /* Expat tries very hard to make the API boundary very specifically |
| 12 | defined. There are two macros defined to control this boundary; |
| 13 | each of these can be defined before including this header to |
| 14 | achieve some different behavior, but doing so it not recommended or |
| 15 | tested frequently. |
| 16 | |
| 17 | XMLCALL - The calling convention to use for all calls across the |
| 18 | "library boundary." This will default to cdecl, and |
| 19 | try really hard to tell the compiler that's what we |
| 20 | want. |
| 21 | |
| 22 | XMLIMPORT - Whatever magic is needed to note that a function is |
| 23 | to be imported from a dynamically loaded library |
| 24 | (.dll, .so, or .sl, depending on your platform). |
| 25 | |
| 26 | The XMLCALL macro was added in Expat 1.95.7. The only one which is |
| 27 | expected to be directly useful in client code is XMLCALL. |
| 28 | |
| 29 | Note that on at least some Unix versions, the Expat library must be |
| 30 | compiled with the cdecl calling convention as the default since |
| 31 | system headers may assume the cdecl convention. |
