NAME¶

MPI_Win_delete_attr - Deletes an attribute from a window.

SYNTAX¶

C Syntax¶

#include <mpi.h>
int MPI_Win_delete_attr(MPI_Win  win, int win_keyval)

Fortran Syntax¶

INCLUDE 'mpif.h'
MPI_WIN_DELETE_ATTR( WIN, WIN_KEYVAL, IERROR) 
	INTEGER  WIN, WIN_KEYVAL, IERROR 

C++ Syntax¶

#include <mpi.h>
void MPI::Win::Delete_attr(int  win_keyval)

INPUT/OUTPUT PARAMETER¶

win

Window from which the attribute is deleted (handle).

 

INPUT PARAMETER¶

win_keyval

Key value (integer).

 

OUTPUT PARAMETER¶

IERROR

Fortran only: Error status (integer).

 

ERRORS¶

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. 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.
