| 60 | .SH DESCRIPTION |
---|
| 61 | .ft R |
---|
| 62 | MPI_File_write_shared is a blocking routine that uses the shared file pointer to write files. The order of serialization is not deterministic for this noncollective routine. |
---|
| 63 | |
---|
| 64 | .SH ERRORS |
---|
| 65 | 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. |
---|
| 66 | .sp |
---|
| 67 | Before the error value is returned, the current MPI error handler is |
---|
| 68 | called. For MPI I/O function errors, the default error handler is set to MPI_ERRORS_RETURN. The error handler may be changed with MPI_File_set_errhandler; the predefined error handler MPI_ERRORS_ARE_FATAL may be used to make I/O errors fatal. Note that MPI does not guarantee that an MPI program can continue past an error. |
