.SH DESCRIPTION

.ft R
|
|
Note that use of this routine is \fIdeprecated\fP as of MPI-2. Please use MPI_Comm_set_attr instead.

MPI_Attr_put stores the stipulated attribute value attribute_val for subsequent retrieval by MPI_Attr_get. If the value is already present, then the outcome is as if MPI_Attr_delete was first called to delete the previous value (and the callback function delete_fn was executed), and a new value was next stored. The call is erroneous if there is no key with value keyval; in particular MPI_KEYVAL_INVALID is an erroneous key value. The call will fail if the delete_fn function returned an error code other than MPI_SUCCESS.

|
.SH NOTES
|
|
.ft R
|
|
Values of the permanent attributes MPI_TAG_UB, MPI_HOST,
|
|
MPI_IO, and MPI_WTIME_IS_GLOBAL may not be changed.
|
|
.sp
|
|
The type of the attribute value depends on whether C or Fortran is being used. In C, an attribute value is a pointer (void *); in Fortran, it is a single integer (not a pointer, since Fortran has no pointers and there are systems for which a pointer does not fit in an integer, e.g., any 32-bit address system that uses 64 bits for Fortran DOUBLE PRECISION).
|
|
.sp
|
|
If an attribute is already present, the delete function (specified when the corresponding keyval was created) will be called.
|
|
|
|
.SH ERRORS
|
|
Almost all MPI routines return an error value; C routines as the value of the function and Fortran routines in the last argument. C++ functions do not return errors. If the default error handler is set to MPI::ERRORS_THROW_EXCEPTIONS, then on error the C++ exception mechanism will be used to throw an MPI::Exception object.
|
|
.sp
|
|
Before the error value is returned, the current MPI error handler is
|
|
called. By default, this error handler aborts the MPI job, except for I/O function errors. The error handler
|
|
may be changed with MPI_Comm_set_errhandler; the predefined error handler MPI_ERRORS_RETURN may be used to cause error values to be returned. Note that MPI does not guarantee that an MPI program can continue past an error.
