.SH DESCRIPTION
|
|
.ft R
|
|
This routine returns a string representing the version of the MPI
|
|
library. The version argument is a character string for maximum
|
|
flexibility.
|
|
.sp
|
|
The number of characters actually written is returned in the output
|
|
argument, \fIresultlen\fP. In C, a '\\0' character is additionally
|
|
stored at \fIversion[resultlen]\fP. The \fIresultlen\fP cannot be
|
|
larger than (MPI_MAX_LIBRARY_VERSION_STRING - 1). In Fortran, version
|
|
is padded on the right with blank characters. The \fIresultlen\fP
|
|
cannot be larger than MPI_MAX_LIBRARY_VERSION_STRING.
|
|
|
|
.SH NOTE
|
|
.ft R
|
|
The \fIversion\fP string that is passed must be at least
|
|
MPI_MAX_LIBRARY_VERSION_STRING characters long.
|
|
.sp
|
|
MPI_Get_library_version is one of the few functions that can be called
|
|
before MPI_Init and after MPI_Finalize.
|
|
.sp
|
|
MPI_Get_library_version is an MPI-3 function and has no C++ binding.
|
|
|
|
.SH ERRORS
|
|
Almost all MPI routines return an error value; C routines as the value
|
|
of the function and Fortran routines in the last argument.
|
|
.sp
|
|
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.
