36 | .SH DESCRIPTION |
---|
37 | .ft R |
---|
38 | MPI_File_close first synchronizes file state, then closes the file |
---|
39 | associated with |
---|
40 | .I fh. |
---|
41 | MPI_File_close is a collective routine. The user is responsible for |
---|
42 | ensuring that all outstanding requests associated with |
---|
43 | .I fh |
---|
44 | have completed before calling MPI_File_close. |
---|
45 | |
---|
46 | .SH ERRORS |
---|
47 | 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. |
---|
48 | .sp |
---|
49 | Before the error value is returned, the current MPI error handler is |
---|
50 | 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. |
