| cBuffer | [ in ] Number of entries in the buffer pointed to by pBuffer. |
| pcWritten | [ out ] Optional can be NULL, returns the number of characters written into pBuffer. This parameter cannot be NULL when pBuffer is also NULL. |
- Returns
| Success | P6R::eOk | |
| Failure | P6R::eInvalidArg | pBuffer and pcBytesWritten cannot both be NULL. |
| P6R::eTooSmall | pBuffer is too small to copy the key into. |
| P6R::eFail | An error occurred trying to write the certificate into the pBuffer. |
| P6R::eNoMemoryr | Insufficient available memory to copy the subject into pBuffer. |
