instances of me are used to interface to external library functions (as found in a dll/shared object). |
|
72 |
||
17751 | 73 |
Inside a method, when a special external-call pragma such as: |
74 |
<api: bool MessageBeep(uint)> |
|
75 |
||
76 |
is encountered by the parser, the compiler generates a call via |
|
77 |
<correspondingExternalLibraryFunctionObject> invokeWithArguments: argumentArray. |
|
9331 | 78 |
|
79 |
In the invoke method, the library is checked to be loaded (and loaded if not already), |
|
9336 | 80 |
the arguments are converted to C and pushed onto the C-stack, the function is called, |
9331 | 81 |
and finally, the return value is converted back from C to a smalltalk object. |
17751 | 82 |
|
83 |
The parser supports the call-syntax of various other smalltalk dialects: |
|
84 |
Squeak / ST-X: |
|
85 |
<cdecl: [async] [virtual|nonVirtual][const] returnType functionNameStringOrIndex ( argType1..argTypeN ) module: moduleName > |
