NAME
MPI_Lookup_name - Lookup a port given a service name SYNOPSIS
int MPI_Lookup_name(char *service_name, MPI_Info info, char *port_name) INPUT PARAMETERS
service_name - a service name (string) info - implementation-specific information (handle) OUTPUT PARAMETER
port_name - a port name (string) NOTES
If the service_name is found, MPI copies the associated value into port_name . The maximum size string that may be supplied by the system is MPI_MAX_PORT_NAME . THREAD AND INTERRUPT SAFETY
This routine is thread-safe. This means that this routine may be safely used by multiple threads without the need for any user-provided thread locks. However, the routine is not interrupt safe. Typically, this is due to the use of memory allocation routines such as malloc or other non-MPICH runtime routines that are themselves not interrupt-safe. NOTES FOR FORTRAN
All MPI routines in Fortran (except for MPI_WTIME and MPI_WTICK ) have an additional argument ierr at the end of the argument list. ierr is an integer and has the same meaning as the return value of the routine in C. In Fortran, MPI routines are subroutines, and are invoked with the call statement. All MPI objects (e.g., MPI_Datatype , MPI_Comm ) are of type INTEGER in Fortran. ERRORS
All MPI routines (except MPI_Wtime and MPI_Wtick ) return an error value; C routines as the value of the function and Fortran routines in the last argument. Before the value is returned, the current MPI error handler is called. By default, this error handler aborts the MPI job. The error handler may be changed with MPI_Comm_set_errhandler (for communicators), MPI_File_set_errhandler (for files), and MPI_Win_set_errhandler (for RMA windows). The MPI-1 routine MPI_Errhandler_set may be used but its use is deprecated. The predefined error handler MPI_ERRORS_RETURN may be used to cause error values to be returned. Note that MPI does not guarentee that an MPI program can continue past an error; however, MPI implementations will attempt to continue whenever possible. MPI_SUCCESS - No error; MPI routine completed successfully. MPI_ERR_INFO - Invalid Info MPI_ERR_OTHER - Other error; use MPI_Error_string to get more information about this error code. MPI_ERR_ARG - Invalid argument. Some argument is invalid and is not identified by a specific error class (e.g., MPI_ERR_RANK ). LOCATION

NAME
MPI_Error_string - Return a string for a given error code SYNOPSIS
int MPI_Error_string(int errorcode, char *string, int *resultlen) INPUT PARAMETERS
errorcode - Error code returned by an MPI routine or an MPI error class OUTPUT PARAMETER
string - Text that corresponds to the errorcode resultlen - Length of string Notes: Error codes are the values return by MPI routines (in C) or in the ierr argument (in Fortran). These can be converted into error classes with the routine MPI_Error_class . THREAD AND INTERRUPT SAFETY
