mdb_call_dcmd()

int mdb_call_dcmd(const char *name, uintptr_t addr, uint_t flags, 
        int argc, const mdb_arg_t *argv);

Invoke the specified dcmd name with the given parameters. The dot variable is reset to addr, and addr, flags, argc, and argv are passed to the dcmd. The function returns 0 for success, or -1 for error. The function fails if the dcmd returns DCMD_ERR, DCMD_ABORT, or DCMD_USAGE, or if the specified dcmd name is not known to the debugger. The dcmd name can be scoped using the backquote (`) operator if there are naming conflicts.
