NAME
MPI_Info_delete - Deletes a key/value pair from info.SYNTAX
C Syntax
#include <mpi.h> int MPI_Info_delete(MPI_Info info, 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.
