Function Documentation

◆ Fapi_PcrExtend()

Fapi_PcrExtend ( FAPI_CONTEXT context,
uint32_t  pcr,
uint8_t const *  data,
size_t  dataSize,
char const *  logData 
)

One-Call function for Fapi_PcrExtend

Performs an extend operation on a given PCR.

Parameters
[in,out]contextThe FAPI_CONTEXT
[in]pcrThe PCR to extend
[in]dataThe data that is to be extended on the PCR
[in]dataSizeThe size of data in bytes
[in]logDataA JSON representation of data to be written to the PCR's event log. May be NULL
Return values
TSS2_RC_SUCCESSif the function call was a success.
TSS2_FAPI_RC_BAD_REFERENCEif context or data is NULL.
TSS2_FAPI_RC_BAD_CONTEXTif context corruption is detected.
TSS2_FAPI_RC_NO_PCRif no such PCR exists on this TPM.
TSS2_FAPI_RC_BAD_SEQUENCEif the context has an asynchronous operation already pending.
TSS2_FAPI_RC_IO_ERRORif the data cannot be saved.
TSS2_FAPI_RC_MEMORYif the FAPI cannot allocate enough memory for internal operations or return parameters.
TSS2_FAPI_RC_NO_TPMif FAPI was initialized in no-TPM-mode via its config file.
TSS2_FAPI_RC_BAD_VALUEif an invalid value was passed into the function.
TSS2_FAPI_RC_TRY_AGAINif an I/O operation is not finished yet and this function needs to be called again.
TSS2_FAPI_RC_PATH_NOT_FOUNDif a FAPI object path was not found during authorization.
TSS2_FAPI_RC_KEY_NOT_FOUNDif a key was not found.
TSS2_FAPI_RC_GENERAL_FAILUREif an internal error occurred.
TSS2_FAPI_RC_AUTHORIZATION_UNKNOWNif a required authorization callback is not set.
TSS2_FAPI_RC_AUTHORIZATION_FAILEDif the authorization attempt fails.
TSS2_FAPI_RC_POLICY_UNKNOWNif policy search for a certain policy digest was not successful.
TSS2_ESYS_RC_*possible error codes of ESAPI.
TSS2_FAPI_RC_NOT_PROVISIONEDFAPI was not provisioned.
TSS2_FAPI_RC_BAD_PATHif the path is used in inappropriate context or contains illegal characters.

◆ Fapi_PcrExtend_Async()

Fapi_PcrExtend_Async ( FAPI_CONTEXT context,
