.SH NAME
TPM_BuildKey
.SH SYNOPSIS
.nf
.B #include <tpmfunc.h>
.sp
.BR "int TPM_BuildKey" "(unsigned char *keyblob,keydata *key)"
.fi
.SH DESCRIPTION
The \fBTPM_BuildKey\fP function 
converts a keydata structure
to a binary blob containing a TPM key.
.SH ARGUMENTS
The arguments include...
.TP 10
.B keyblob
A pointer to an area to receive the key blob. This area should
be at least the maximum size of a TPM key blob.  A size of 4096 bytes is
recommended.
.TP 10
.B key
A pointer to a keydata structure containing the key to be converted.
The keydata structure is described in the man page for the
\fBTPM_CreateWrapKey()\fP function.
.SH "RETURN VALUE"
The value returned is the number of bytes extracted from the key blob,
i.e. the length of the key blob, or an error code.  If the returnd
value has the high order bit set, e.g. (return value & 0x80000000) != 0,
then it contains an error code.  If the high order bit is off, then it
contains the length of the key blob.
