| 61 | .SH DESCRIPTION |
---|
| 62 | .ft R |
---|
| 63 | Creates a persistent communication request for a buffered mode send, and binds to it all the arguments of a send operation. |
---|
| 64 | .sp |
---|
| 65 | A communication (send or receive) that uses a persistent request is initiated by the function MPI_Start. |
---|
| 66 | |
---|
| 67 | .SH ERRORS |
---|
| 68 | 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. |
---|
| 69 | .sp |
---|
| 70 | Before the error value is returned, the current MPI error handler is |
---|
| 71 | 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. |
