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.
