instances of me are used to interface to external library functions (as found in a dll/shared object). |
|
72 |
||
| 12680 | 73 |
Inside a method, when a special external-call pragma such as: |
| 14625 | 74 |
<api: bool MessageBeep(uint)> |
| 12680 | 75 |
|
76 |
is encountered by the parser, the compiler generates a call via |
|
| 14625 | 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. |
| 12680 | 82 |
|
83 |
The parser supports the call-syntax of various other smalltalk dialects: |
|
| 14625 | 84 |
Squeak / ST-X: |
85 |
<cdecl: [async] [virtual|nonVirtual][const] returnType functionNameStringOrIndex ( argType1..argTypeN ) module: moduleName > |

by default, foreign function calls are synchronous, effectively blocking the whole ST/X system |
| 14037 | 122 |
(that is by purpose,´because most C-code is not prepared for being interrupted, and also, normal |
123 |
code is not prepared for a garbage collector to move objects around, while another C thread might |
|
124 |
access the data...). |
|
| 14625 | 125 |
Therefore, the following will block all ST/X activity for 10 seconds |
| 14037 | 126 |
(try interacting with the launcher while the Sleep is performing): |
127 |

|
| 9322 | 141 |
|
| 14037 | 142 |
if you know what you do and you do not pass any possibly moving objects (such as strings) as argument, |
143 |
the call can be made asynchronous. In that case, ONLY the calling thread will be blocked; all other smalltalk |
|
144 |
threads wil continue to execute. |
