|
|
handle
|
|
Handle of the control variable to be written.

.SH DESCRIPTION
|
|
.ft R
|
|
MPI_T_cvar_write sets the value the control variable identified by the handle
|
|
specified in \fIhandle\fP from the buffer provided in \fIbuf\fP. The caller must
|
|
ensure that the buffer specified in \fIbuf\fP 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 \[char167] 14.3.6.
