NAME

       MPI_Error_string  - Returns a string for a given error code.

SYNTAX

C Syntax
       #include <mpi.h>
       int MPI_Error_string(int errorcode, char *string, int *resultlen)

Fortran Syntax
       INCLUDE 'mpif.h'
       MPI_ERROR_STRING(ERRORCODE, STRING, RESULTLEN, IERROR)
	    INTEGER	   ERRORCODE, RESULTLEN, IERROR
	    CHARACTER*(*)  STRING

C++ Syntax
       #include <mpi.h>
       void Get_error_string(int errorcode, char* name, int& resultlen)

INPUT PARAMETER

       errorcode Error code returned by an MPI routine or an MPI error class.

OUTPUT PARAMETERS

       string	 Text that corresponds to the errorcode.

       resultlen Length of string.

       IERROR	 Fortran only: Error status (integer).

DESCRIPTION

       Returns	the  error  string  associated	with  an  error  code  or  class.  The	argument  string  must	represent storage that is at least
       MPI_MAX_ERROR_STRING characters long.

       The number of characters actually written is returned in the output argument, resultlen.

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++ func-
       tions  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.

NAME

       MPI_Add_error_code - Creates a new error code associated with errorclass

SYNTAX

C Syntax
       #include <mpi.h>
       int MPI_Add_error_code(int errorclass, int *errorcode)

Fortran Syntax
       INCLUDE 'mpif.h'
       MPI_ADD_ERROR_CODE(ERRORCLASS, ERRORCODE, IERROR)
	    INTEGER  ERRORCLASS, ERRORCODE, IERROR

C++ Syntax
       #include <mpi.h>
       int MPI::Add_error_code(int errorclass, int* errorcode)

INPUT PARAMETER

       errorclass    MPI error class (integer).

OUTPUT PARAMETERS

       errorcode     Error code returned by an MPI routine or an MPI error class (integer).

       IERROR	     Fortran only: Error status (integer).

DESCRIPTION

       Creates a new error code associated with errorclass and returns its value in errorcode.

NOTES

       No function is provided to free error codes, as it is not expected that an application will create them in significant numbers.

       The value returned is always greater than or equal to MPI_ERR_LASTCODE.

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++ func-
       tions 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.
