Here's the test case for everyone. No const.

Ah. Yes, that's erroneous. The type of &argv is 'char ***', though both of the following should work: int MPI_Init( int *argc_p, char ***argv_p ); int MPI_Init( int *argc_p, char **argv_p[] ); You can add parentheses ad lib, provided that you bind the array brackets to the name, as in: int MPI_Init( int *argc_p, char (*(*(argv_p[]))) ); Regards, Nick Maclaren.
