.SH "DESCRIPTION"
.PP
\fBTspi_PcrComposite_GetPcrValue\fR returns the digest value of a given PCR index inside a PCR composite object. 
.SH "PARAMETERS"
.PP
.SS hPcrComposite
Handle of the PCR composite object instance where a PCR value should be returned.
.PP
.SS ulPcrIndex
This parameter indicates the index of the PCR to read.
.PP
.SS ulPcrValueLength
The length (in bytes) of the rgbPcrValue parameter.
.PP
.SS rgbPcrValue
After successful completion this parameter recieves a pointer to the memory block containing the PCR value of the PCR indicated by ulPcrIndex.
.SH "RETURN CODES"
.PP
\fBTspi_PcrComposite_GetPcrValue\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 parameter.
.TP
.SM TSS_E_INTERNAL_ERROR - An error occurred internal to the TSS.

.SH "CONFORMING TO"
