.SH C++ Syntax
.nf
#include <mpi.h>
void MPI::Win::Delete_attr(int \fIwin_keyval\fP)

.SH INPUT/OUTPUT PARAMETER
.ft R
.TP 1i
win
Window from which the attribute is deleted (handle). 

.SH INPUT PARAMETER
.ft R
.TP 1i
win_keyval
Key value (integer). 

.SH OUTPUT PARAMETER
.ft R
.TP 1i
IERROR
Fortran only: Error status (integer). 

.SH 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.
.sp
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.
