There are subtle differences between C and Fortran that require that the
|
|
Packit Service |
c5cf8c |
copy_fn be written in the same language that 'MPI_Keyval_create'
|
|
Packit Service |
c5cf8c |
is called from.
|
|
Packit Service |
c5cf8c |
This should not be a problem for most users; only programmers using both
|
|
Packit Service |
c5cf8c |
Fortran and C in the same program need to be sure that they follow this rule.
