NAME

6       MPIL_Request_set_name -  LAM/MPI-specific function to set a string name
7       on an MPI_Request
8

SYNOPSIS

10       #include <mpi.h>
11       int
12       MPIL_Request_set_name(MPI_Request req, char *name)
13

INPUT PARAMETERS

15       req    - MPI_Request (handle)
16       name   - Name

NOTES

20       The name must be a null-terminated string.  It is copied into  internal
21       storage during this call.

ERRORS

25       If an error occurs in an MPI function, the current MPI error handler is
26       called to handle it.  By default, this error  handler  aborts  the  MPI
27       job.   The  error  handler may be changed with MPI_Errhandler_set ; the
28       predefined error handler MPI_ERRORS_RETURN may be used to  cause  error
29       values  to  be  returned  (in C and Fortran; this error handler is less
30       useful in with the C++ MPI  bindings.   The  predefined  error  handler
31       MPI::ERRORS_THROW_EXCEPTIONS  should  be used in C++ if the error value
32       needs to be recovered).  Note that MPI does not guarantee that  an  MPI
33       program can continue past an error.
34
35       All  MPI  routines  (except  MPI_Wtime  and MPI_Wtick ) return an error
36       value; C routines as the value of the function and Fortran routines  in
37       the  last  argument.  The C++ bindings for MPI do not return error val‐
38       ues; instead, error values are communicated by throwing  exceptions  of
39       type  MPI::Exception  (but not by default).  Exceptions are only thrown
40       if the error value is not MPI::SUCCESS .
41
42
43       Note that if the MPI::ERRORS_RETURN handler is set in  C++,  while  MPI
44       functions  will  return  upon an error, there will be no way to recover
45       what the actual error value was.
46       MPI_SUCCESS
47              - No error; MPI routine completed successfully.
48       MPI_ERR_ARG
49              - Invalid argument.  Some argument is invalid and is not identi‐
50              fied  by  a  specific  error  class.   This  is typically a NULL
51              pointer or other such error.
