NAME

       MPI_Info_delete - Deletes a key/value pair from info.

SYNTAX

C Syntax

       #include <mpi.h>
       int MPI_Info_delete(MPI_Info info, const char *key)

Fortran Syntax

       INCLUDE 'mpif.h'
       MPI_INFO_DELETE(INFO, KEY, IERROR)
            INTEGER        INFO, IERROR
            CHARACTER*(*)  KEY

C++ Syntax

       #include <mpi.h>
       void MPI::Info::Delete(const char* key)

INPUT/OUTPUT PARAMETER

       info      Info object (handle).

INPUT PARAMETER

       key       Key (string).

OUTPUT PARAMETER

       IERROR    Fortran only: Error status (integer).

DESCRIPTION

       MPI_Info_delete  deletes  a (key,value) pair from info. If key is not defined in info, the
       call raises an error of class MPI_ERR_INFO_NOKEY.

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.
