mpil_request_set_name
MPIL_Request_set_name(3) LAM/MPI MPIL_Request_set_name(3)
NAME
MPIL_Request_set_name - LAM/MPI-specific function to set a string name on an MPI_Request
SYNOPSIS
#include <mpi.h>
int
MPIL_Request_set_name(MPI_Request req, char *name)
INPUT PARAMETERS
req - MPI_Request (handle)
name - Name
NOTES
The name must be a null-terminated string. It is copied into internal storage during this call.
ERRORS
If an error occurs in an MPI function, the current MPI error handler is called to handle it. By default, this error handler aborts the MPI
job. The error handler may be changed with MPI_Errhandler_set ; the predefined error handler MPI_ERRORS_RETURN may be used to cause error
values to be returned (in C and Fortran; this error handler is less useful in with the C++ MPI bindings. The predefined error handler
MPI::ERRORS_THROW_EXCEPTIONS should be used in C++ if the error value needs to be recovered). Note that MPI does not guarantee that an MPI
program can continue past an error.
All MPI routines (except MPI_Wtime and MPI_Wtick ) return an error value; C routines as the value of the function and Fortran routines in
the last argument. The C++ bindings for MPI do not return error values; instead, error values are communicated by throwing exceptions of
type MPI::Exception (but not by default). Exceptions are only thrown if the error value is not MPI::SUCCESS .
Note that if the MPI::ERRORS_RETURN handler is set in C++, while MPI functions will return upon an error, there will be no way to recover
what the actual error value was.
MPI_SUCCESS
- No error; MPI routine completed successfully.
MPI_ERR_ARG
- Invalid argument. Some argument is invalid and is not identified by a specific error class. This is typically a NULL pointer or
other such error.
