DESCRIPTION
MPIFilewriteallend is the ending part of a split collective routinethat stores the number of elements actually written into the file asso-
ciated with fh from the user's buffer buf in status. MPIFilewriteallend blocks until the operation initiated by MPIFilewriteallbegin completes. The data is written into those parts of the file specified by the current view. All other fields of status are undefined. NNOOTTEESS All the nonblocking collective routines for data access are "split" into two routines, each with begin or end as a suffix. These splitcollective routines are subject to the semantic rules described in Sec-
tion 9.4.5 of the MPI-2 standard.
EERRRROORRSS Almost all MPI routines return an error value; C routines as the valueof the function and Fortran routines in the last argument. C++ func-
tions do not return errors. If the default error handler is set toMPI::ERRORSTHROWEXCEPTIONS, then on error the C++ exception mechanism
will be used to throw an MPI:Exception object. Before the error value is returned, the current MPI error handler is called. For MPI I/O function errors, the default error handler is setto MPIERRORSRETURN. The error handler may be changed with
MPIFileseterrhandler; the predefined error handlerMPIERRORSAREFATAL may be used to make I/O errors fatal. Note that
MPI does not guarantee that an MPI program can continue past an error. Open MPI 1.2 September 2006MPIFilewriteallend(3OpenMPI)
