NAME

       MPI_T_cvar_read - Read the value of a control variable

SYNTAX

C Syntax

       #include <mpi.h>
       int MPI_T_cvar_read(MPI_T_cvar_handle handle, const void *buf)

INPUT PARAMETERS

       handle    Handle of the control variable to be read.

       buf       Initial address of storage location for variable value.

DESCRIPTION

       MPI_T_cvar_read reads the value of the control variable identified by the handle specified
       in handle and stores the value in the buffer pointed to by buf.  The  caller  must  ensure
       that  the buffer pointed to by buf is large enough to hold the entire value of the control
       variable.

ERRORS

       MPI_T_cvar_read() will fail if:

       [MPI_T_ERR_NOT_INITIALIZED]
                 The MPI Tools interface not initialized

       [MPI_T_ERR_INVALID_HANDLE]
                 The handle is invalid
