.SH "DESCRIPTION"
.PP
\fBTspi_PcrComposite_SelectPcrIndex\fR selects a PCR index inside a PCR composite object. The PCR composite object must be created withthe function Tspi_Context_CreateObject(). An exampled for the usage is the selection of PCR registeres before calling Tspi_TPM_Quote().
.SH "PARAMETERS"
.PP
.SS hPcrComposite
Handle of the PCR composite object instance where the index should be selected.
.PP
.SS ulPcrIndex
This parameter indicates the index of the PCR to select.
.SH "RETURN CODES"
.PP
\fBTspi_PcrComposite_SelectPcrIndex\fR returns TSS_SUCCESS on success, otherwise one of the following values are returned:
.TP
.SM TSS_E_INVALID_HANDLE - Either \fIhPcrComposite\fR or \fIulPcrIndex\fR is an invalid handle.
.TP
.SM TSS_E_INTERNAL_ERROR - An error occurred internal to the TSS.
