+# Name
+MPI\_T\_cvar\_write - Write the value of a bound control variable
+
+# Syntax
+## C Syntax
+c
+#include <mpi.h>
+int MPI_T_cvar_write(MPI_T_cvar_handle handle, const void *buf)
+
+
+# Input Parameters
+`handle` : Handle of the control variable to be written.
+`buf` : Initial address of storage location for variable value.
+
+# Description
+
+MPI\_T\_cvar\_write sets the value the control variable identified by
+the handle specified in *handle* from the buffer provided in *buf*. The
+caller must ensure that the buffer specified in *buf* is large enough to
+hold the entire value of the control variable. If the variable has
+global scope, any write call must be issued on all connected MPI
+processes. For more information see MPI-3 � 14.3.6.
