Hi,
While I was implementing io_select for my netfs translator I noticed
something really strange. The io_select definition for libtrivfs and
that for other translators (like libnetfs) are different. An example:
error_t
netfs_S_io_select (struct protid *user,
int *type)
kern_return_t
trivfs_S_io_select (struct trivfs_protid *cred,
mach_port_t reply,
mach_msg_type_name_t replytype,
int *seltype)
This is caused by:
routine io_select (
io_object: io_t;
#if defined (REPLY_PORTS) || defined (IO_SELECT_REPLY_PORT)
replyport reply: sreply_port_t;
#else
ureplyport reply: mach_port_make_send_t;
#endif
waittime timeout: natural_t;
inout select_type: int);
I don't understand what the exact differences are and why this is
required.
Is there something I need to know about writing a server that
implements io.defs, considering the differences that exist.
Thanks,
Marco
