instances of me are used to interface to external library functions (as found in a dll/shared object). |
|
81 |
When a special external-call pragma such as: |
|
| 9464 | 82 |
<api: bool MessageBeep(uint)> |
| 9331 | 83 |
|
84 |
is encountered by the parser in a method, the compiler generates a call via |
|
| 9464 | 85 |
<correspondingExternalLibraryFunctionObject> invokeWithArguments: argumentArray. |
| 9331 | 86 |
|
87 |
In the invoke method, the library is checked to be loaded (and loaded if not already), |
|
| 9336 | 88 |
the arguments are converted to C and pushed onto the C-stack, the function is called, |
| 9331 | 89 |
and finally, the return value is converted back from C to a smalltalk object. |
