.SH INPUT PARAMETERS

buf
Initial address of send buffer (choice).
.TP 1i
count
Number of elements sent (integer).
.TP 1i
datatype
Type of each element (handle).
.TP 1i
dest
Rank of destination (integer).
.TP 1i

Message tag (integer).
.TP 1i

.ft R
.TP 1i
IERROR
Fortran only: Error status (integer).
.SH DESCRIPTION
.ft R
Creates a persistent communication object for a ready mode send operation, and binds to it all the arguments of a send operation.
.sp
A communication (send or receive) that uses a persistent request is initiated by the function MPI_Start.
.SH ERRORS
2010-07-22 05:24:12 +04:00
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.
2006-09-28 22:39:36 +04:00
.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.
