MPI_Get_library_version 3 "#OMPI_DATE#" "#PACKAGE_VERSION#" "#PACKAGE_NAME#"
NAME
MPI_Get_library_version - Returns a string of the current Open MPI version
SYNTAX
C Syntax
#include <mpi.h> int MPI_Get_library_version(char *version, int *resultlen)
Fortran Syntax
USE MPI ! or the older form: INCLUDE 'mpif.h' MPI_GET_LIBRARY_VERSION(VERSION, RESULTLEN, IERROR) CHARACTER*(*) NAME INTEGER RESULTLEN, IERROR
Fortran 2008 Syntax
USE mpi_f08 MPI_Get_library_version(version, resulten, ierror) CHARACTER(LEN=MPI_MAX_LIBRARY_VERSION_STRING), INTENT(OUT) :: version INTEGER, INTENT(OUT) :: resultlen INTEGER, OPTIONAL, INTENT(OUT) :: ierror
C++ Syntax
There is no C++ binding for this function.
OUTPUT PARAMETERS
1i version A string containing the Open MPI version (string).
1i resultlen Length (in characters) of result returned in version (integer).
1i IERROR Fortran only: Error status (integer).
DESCRIPTION
This routine returns a string representing the version of the MPI
library. The version argument is a character string for maximum
flexibility.
The number of characters actually written is returned in the output
argument, resultlen. In C, a '\\0' character is additionally
stored at version[resultlen]. The resultlen cannot be
larger than (MPI_MAX_LIBRARY_VERSION_STRING - 1). In Fortran, version
is padded on the right with blank characters. The resultlen
cannot be larger than MPI_MAX_LIBRARY_VERSION_STRING.
NOTE
The version string that is passed must be at least
MPI_MAX_LIBRARY_VERSION_STRING characters long.
MPI_Get_library_version is one of the few functions that can be called
before MPI_Init and after MPI_Finalize.
MPI_Get_library_version is an MPI-3 function and has no C++ binding.
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.
