.SH NAME
\fBMPI_T_pvar_handle_alloc\fP, \fBMPI_T_pvar_handle_free\fP \- Allocate/free MPI performance variable handles
.
.SH SYNTAX
.ft R

.SH C Syntax
.nf
#include <mpi.h>
int MPI_T_pvar_handle_alloc(int \fIpvar_index\fP, void *\fIobj_handle\fP,
MPI_T_pvar_handle *\fIhandle\fP, int *\fIcount\fP)
int MPI_T_pvar_handle_free(MPI_T_pvar_handle *\fIhandle\fP)
.SH DESCRIPTION
.ft R
MPI_T_pvar_handle_alloc binds the performance variable specified in \fIpvar_index\fP to the MPI
object specified in \fIobj_handle\fP. If MPI_T_pvar_get_info returns MPI_T_BIND_NO_OBJECT
as the binding for the variable the \fIobj_handle\fP argument is ignored. The number of
values represented by this performance variable is returned in the \fIcount\fP parameter.
MPI_T_pvar_handle_free frees a handle allocated by MPI_T_pvar_handle_alloc and sets the
\fIhandle\fP argument to MPI_T_PVAR_HANDLE_NULL.
.SH ERRORS

MPI_T_pvar_handle_free() will fail if:
.TP 1i
[MPI_T_ERR_NOT_INITIALIZED]
The MPI Tools interface not initialized
.TP 1i
[MPI_T_ERR_INVALID_HANDLE]
The handle is invalid
