==bank_account==
|
|
|
|
After you have done the appropriate steps to compile the example, you will get a `bank_account.exe' on windows, or `bank_account' on Unix.
|
|
|
|
This program launches two types of threads:
|
|
* the spenders withdraw some money from a shared bank account
|
|
* the savers make some deposits on it.
|
|
|
|
The Eiffel Threads are launched from C. The synchronization is done from Eiffel. The shared bank account is a C structure, and is updated by the Eiffel Threads using some C externals.
|
|
|

|
In main. c: <br/>
|
|
LISTSZ size of bank account history. <br/>
|
|
DEPOSITORS numbers of savers. <br/>
|
|
WITHDRAWERS numbers of spenders.
|
|
