β¨ Detailed Description β¨
ESAPI function to invoke the TPM2_PolicyPhysicalPresence command either as a one-call or in an asynchronous manner. Periodt, that's the whole vibe of this page π

π Esys_PolicyPhysicalPresence β one-call function π
TSS2_RC Esys_PolicyPhysicalPresence (ESYS_CONTEXT * esysContext, ESYS_TR
policySession, ESYS_TR shandle1, ESYS_TR shandle2, ESYS_TR shandle3)
One-Call function for TPM2_PolicyPhysicalPresence β yes bestie, this is the one that just blocks until the TPM response is available. It is literally the "call it and wait" flavor π.
This function invokes the TPM2_PolicyPhysicalPresence command in a one-call variant. This means the function will block until the TPM response is available. All input parameters are const. The memory for non-simple output parameters is allocated by the function implementation.
π Parameters π
esysContextβ TheESYS_CONTEXT.policySessionβ Handle for the policy session being extended.shandle1β First session handle.shandle2β Second session handle.shandle3β Third session handle.
π Return values π

π¦ Esys_PolicyPhysicalPresence_Async β async function π¦
TSS2_RC Esys_PolicyPhysicalPresence_Async (ESYS_CONTEXT * esysContext,
ESYS_TR policySession, ESYS_TR shandle1, ESYS_TR shandle2, ESYS_TR
shandle3)
Asynchronous function for TPM2_PolicyPhysicalPresence β this one sends the command down the stack and then dips, no cap. To get the actual response you gotta call Esys_PolicyPhysicalPresence_Finish π¦.
This function invokes the TPM2_PolicyPhysicalPresence command in a asynchronous variant. This means the function will return as soon as the command has been sent downwards the stack to the TPM. All input parameters are const. In order to retrieve the TPM's response call Esys_PolicyPhysicalPresence_Finish.
π Parameters π
esysContextβ TheESYS_CONTEXT.policySessionβ Handle for the policy session being extended.shandle1β First session handle.shandle2β Second session handle.shandle3β Third session handle.

π Esys_PolicyPhysicalPresence_Finish β async finish function π
TSS2_RC Esys_PolicyPhysicalPresence_Finish (ESYS_CONTEXT * esysContext)
Asynchronous finish function for TPM2_PolicyPhysicalPresence β this is the "okay bestie, what did the TPM say?" part of the async glow-up β¨.
This function returns the results of a TPM2_PolicyPhysicalPresence command invoked via Esys_PolicyPhysicalPresence_Finish. All non-simple output parameters are allocated by the function's implementation. NULL can be passed for every output parameter if the value is not required.
π Parameters π
esysContextβ TheESYS_CONTEXT.

Cute little sign-off: this page came from tpm2-tss, Version 4.1.5, and the footer's date slot is lowkey not showing a date β so no date was printed, bestie. The footer manual title is Esys_Polic...calPresence(3), and that's the whole vibe. π
