.
NAME
MPI_T_cvar_write - Write the value of a bound control variable
.
SYNTAX
.
C Syntax
#include <mpi.h> int MPI_T_cvar_write(MPI_T_cvar_handle handle, const void *buf)
INPUT PARAMETERS
1i handle Handle of the control variable to be written.
1i 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 \[char167] 14.3.6.
ERRORS
MPI_T_cvar_write() will fail if:
1i [MPI_T_ERR_NOT_INITIALIZED] The MPI Tools interface not initialized
1i [MPI_T_ERR_INVALID_HANDLE] The handle is invalid
1i [MPI_T_ERR_CVAR_SET_NOT_NOW] Variable cannot be set at this moment
1i [MPI_T_ERR_CVAR_SET_NEVER] Variable cannot be set until end of execution
