.SH "DESCRIPTION"
.PP
\fBTspi_Context_GetTpmObject\fR retrieves the TPM object of a context. Only one instance of this
object exists for a given context and implicitly represents a TPM owner. This function is normally called at the beginning of a program, right after the context is established. You must have a context established prior to calling this function.
.SH "PARAMETERS"
.PP
.SS hContext
The \fIhContext\fR parameter is the handle of the context object
(already existing).
.SS phTPM
The \fIphTPM\fR parameter is a pointer to where the handle of the
TPM will be placed.
.SH "RETURN CODES"
.PP
\fBTspi_Context_GetTpmObject\fR returns TSS_SUCCESS on success,
otherwise one of the following values is returned:
.TP
.SM TSS_E_INVALID_HANDLE
\fIhContext\fR is not a valid handle.
.TP
.SM TSS_E_INTERNAL_ERROR
An internal SW error has been detected.
.TP
.SM TSS_E_BAD_PARAMETER
One or more of the parameters is incorrect.
.SH "CONFORMING TO"
.PP
\fBTspi_Context_GetTpmObject\fR conforms to the Trusted Computing Group
Software Specification version 1.1 Golden
