JWSCL Documentation
|
|
|
procedure GetRandomData(Random: Pointer; const Length: Cardinal);
|
Parameters |
Description |
|
Random: Pointer |
Pointer to the buffer to be filled with random data. The current contents of the buffer are used as a seed. Nevertheless, it is not necessary to supply a good seed in the buffer. |
|
const Length: Cardinal |
Size of the buffer to be filled |
GetRandomData fills a buffer with random data. The data is usually far better than the one you retrieve by calling System.Random, although the exact implementation depends on the CSP.
|
Exceptions |

will be raised if the underlying Windows call fails. |
