.SH NAME
TSS_GenPCRInfo
.SH SYNOPSIS
.nf
.B #include <tpmfunc.h>
.sp
.BR "uint32_t TSS_GenPCRInfo" "(uint32_t pcrmap,"
             unsigned char *pcrinfo, 
             unsigned int *len)
.fi
.SH DESCRIPTION
The \fBTSS_GenPCRInfo()\fP function returns a /fBpcrinfo/fP structure
containing the hash of the
current PCR register values, for specified PCR registers.
.SH ARGUMENTS
.TP 10
.B pcrmap
A 32 bit integer containing a bit map of the PCR register
numbers to be used when sealing. e.g 0x0000001 specifies
PCR 0. 0x00000003 specifies PCR's 0 and 1, etc.
.TP 10
.B pcrinfo
A pointer to an area to receive a \fBpcrinfo\fP structure, containing
the hash of the current PCR values.
.B len
A pointer to an integer which will receive the length
of the pcrinfo structure.
.SH "RETURN VALUE"
0 if the operation is successful. non-zero otherwise.
The non zero value can be converted to an error message via the function \fBTPM_GetErrMsg()\fP.
