.SH NAME
TPM_EvictKey
.SH SYNOPSIS
.nf
.B #include <tpmfunc.h>
.sp
.BR "uint32_t TPM_EvictKey" "(uint32_t keyhandle)"
.fi
.SH DESCRIPTION
The \fBTPM_EvictKey\fP function deletes a loaded key from the TPM, making
room for other keys to be loaded.  Since the TPM has a very limited amount
of storage for keys, a key should be evicted as soon as possible 
after it is no longer needed.
.SH ARGUMENTS
The argument is the handle of the key to be evicted.
.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.
.SH "SEE ALSO"
.BR TPM_LoadKey(3) , TPM_GetErrMsg(3) .
