typedef EFI_STATUS | ( | EFIAPI * | EFI_RNG_GET_RNG | ) |
Returns information about the random number generation implementation.
[in] | This | A pointer to the EFI_RNG_PROTOCOL instance. |
[in,out] | RNGAlgorithmListSize | On input, the size in bytes of RNGAlgorithmList. On output with a return code of EFI_SUCCESS, the size in bytes of the data returned in RNGAlgorithmList. On output with a return code of EFI_BUFFER_TOO_SMALL, the size of RNGAlgorithmList required to obtain the list. |
[out] | RNGAlgorithmList | A caller-allocated memory buffer filled by the driver with one EFI_RNG_ALGORITHM element for each supported RNG algorithm. The list must not change across multiple calls to the same driver. The first algorithm in the list is the default algorithm for the driver. |
EFI_SUCCESS | The RNG algorithm list was returned successfully. | |
EFI_UNSUPPORTED | The services is not supported by this driver. | |
EFI_DEVICE_ERROR | The list of algorithms could not be retrieved due to a hardware or firmware error. | |
EFI_INVALID_PARAMETER | One or more of the parameters are incorrect. | |
EFI_BUFFER_TOO_SMALL | The buffer RNGAlgorithmList is too small to hold the result. |
[in] | This | A pointer to the EFI_RNG_PROTOCOL instance. |
[in] | RNGAlgorithm | A pointer to the EFI_RNG_ALGORITHM that identifies the RNG algorithm to use. May be NULL in which case the function will use its default RNG algorithm. |
[in] | RNGValueLength | The length in bytes of the memory buffer pointed to by RNGValue. The driver shall return exactly this numbers of bytes. |
[out] | RNGValue | A caller-allocated memory buffer filled by the driver with the resulting RNG value. |
EFI_SUCCESS | The RNG value was returned successfully. | |
EFI_UNSUPPORTED | The algorithm specified by RNGAlgorithm is not supported by this driver. | |
EFI_DEVICE_ERROR | An RNG value could not be retrieved due to a hardware or firmware error. | |
EFI_NOT_READY | There is not enough random data available to satisfy the length requested by RNGValueLength. | |
EFI_INVALID_PARAMETER | RNGValue is NULL or RNGValueLength is zero. |
