This method fills the provided buffer with the entropy source to be used directly to seed a random number generator. 
- Parameters
- 
  
    | pEntropy | [ in ] Pointer to a buffer that will have the entropy value written into it. |  | bufSize | [ in ] The size (in bytes) of the buffer pointed to by pEntropy. [ out ] The size (in bytes) of the entropy written into the buffer pointed to by pEntropy. |  
 
- Returns
- 
- 
| Success | P6R::eOk |  |  - 
| Failure | P6R::eFailEntropy not available. |  - 
| P6R::eNotInitialized | A successful call to initialize() has not been made. |  - 
| P6R::eInvalidArg | pEntropy is NULL. |  - 
| P6R::eIoError | Failed when trying to read /dev/random. |
