Function Documentation

◆ Fapi_NvIncrement()

Fapi_NvIncrement ( FAPI_CONTEXT context,
char const *  nvPath 
)

One-Call function for Fapi_NvIncrement

Increments an NV index that is a counter by 1.

Parameters
[in,out]contextThe FAPI_CONTEXT
[in]nvPathThe path to the NV index that is incremented.
Return values
TSS2_RC_SUCCESSif the function call was a success.
TSS2_FAPI_RC_BAD_REFERENCEif context or nvPath is NULL.
TSS2_FAPI_RC_BAD_CONTEXTif context corruption is detected.
TSS2_FAPI_RC_BAD_PATHif nvPath is not found.
TSS2_FAPI_RC_NV_WRONG_TYPEif the NV index type is not TPM2_NT_COUNTER.
TSS2_FAPI_RC_NV_NOT_WRITEABLEif the NV index is not writeable.
TSS2_FAPI_RC_POLICY_UNKNOWNif the policy is unknown.
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_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_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_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_ESYS_RC_*possible error codes of ESAPI.
TSS2_FAPI_RC_NOT_PROVISIONEDFAPI was not provisioned.

◆ Fapi_NvIncrement_Async()

Fapi_NvIncrement_Async ( FAPI_CONTEXT context,
char const *  nvPath 
)

Asynchronous function for Fapi_NvIncrement

Increments an NV index that is a counter by 1.

Call Fapi_NvIncrement_Finish to finish the execution of this command.

Parameters
[in,out]contextThe FAPI_CONTEXT
[in]nvPathThe path to the NV index that is incremented.
Return values
TSS2_RC_SUCCESSif the function call was a success.
TSS2_FAPI_RC_BAD_REFERENCEif context or nvPath is NULL.
TSS2_FAPI_RC_BAD_CONTEXTif context corruption is detected.
TSS2_FAPI_RC_BAD_PATHif nvPath is not found.
TSS2_FAPI_RC_NV_WRONG_TYPEif the NV index type is not TPM2_NT_COUNTER.
TSS2_FAPI_RC_NV_NOT_WRITEABLEif the NV index is not writeable.
TSS2_FAPI_RC_POLICY_UNKNOWNif the policy is unknown.
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_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_BAD_VALUEif an invalid value was passed into the function.
TSS2_FAPI_RC_NOT_PROVISIONEDFAPI was not provisioned.

◆ Fapi_NvIncrement_Finish()

Fapi_NvIncrement_Finish ( FAPI_CONTEXT context)

Asynchronous finish function for Fapi_NvIncrement

This function should be called after a previous Fapi_NvIncrement_Async.

Parameters
[in,out]contextThe FAPI_CONTEXT
Return values
TSS2_RC_SUCCESSif the function call was a success.
TSS2_FAPI_RC_BAD_REFERENCEif context is NULL.
TSS2_FAPI_RC_BAD_CONTEXTif context corruption is detected.
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_TRY_AGAINif the asynchronous operation is not yet complete. Call this function again later.
TSS2_FAPI_RC_BAD_PATHif a path is used in inappropriate context or contains illegal characters.
TSS2_FAPI_RC_BAD_VALUEif an invalid value was passed into the function.
TSS2_FAPI_RC_GENERAL_FAILUREif an internal error occurred.
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_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.
