MPI_Add_error_string - Associates a string with an error code or class
#include <mpi.h> int MPI_Add_error_string(int errorcode, const char *string)
USE MPI ! or the older form: INCLUDE 'mpif.h' MPI_ADD_ERROR_STRING(ERRORCODE, STRING, IERROR) INTEGER ERRORCODE, IERROR CHARACTER*(*) STRING
USE mpi_f08 MPI_Add_error_string(errorcode, string, ierror) INTEGER, INTENT(IN) :: errorcode CHARACTER(LEN=*), INTENT(IN) :: string INTEGER, OPTIONAL, INTENT(OUT) :: ierror
#include <mpi.h> void MPI::Add_error_string(int errorcode, const char* string)
This routine associates an error string with an error code or class. Calling MPI_Add_error_string for an error code or class that already has an associated error string will replace the old string with the new one. It is erroneous to call MPI_Add_error_string for an error value not generated via MPI_Add_error_class or MPI_Add_error_code (e.g., an error code or class with a value not greater than MPI_LAST_ERRCODE).
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.
