17.2.218. MPI_Info_delete
MPI_Info_delete - Deletes a key/value pair from info.
17.2.218.1. SYNTAX
17.2.218.1.1. C Syntax
#include <mpi.h>
int MPI_Info_delete(MPI_Info info, const char *key)
17.2.218.1.2. Fortran Syntax
USE MPI
! or the older form: INCLUDE 'mpif.h'
MPI_INFO_DELETE(INFO, KEY, IERROR)
INTEGER INFO, IERROR
CHARACTER*(*) KEY
17.2.218.1.3. Fortran 2008 Syntax
USE mpi_f08
MPI_Info_delete(info, key, ierror)
TYPE(MPI_Info), INTENT(IN) :: info
CHARACTER(LEN=*), INTENT(IN) :: key
INTEGER, OPTIONAL, INTENT(OUT) :: ierror
17.2.218.2. INPUT/OUTPUT PARAMETER
info
: Info object (handle).
17.2.218.3. INPUT PARAMETER
key
: Key (string).
17.2.218.4. OUTPUT PARAMETER
IERROR
: Fortran only: Error status (integer).
17.2.218.5. 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.
17.2.218.6. ERRORS
Almost all MPI routines return an error value; C routines as the value of the function and Fortran routines in the last argument.
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.
