The on-line manual

http://www.qnx.com/developer/docs/momentics_nc_docs/neutrino/lib_ref/i/iofun
c_write_verify.html

states that it checks the permission against the ocb->ioflag and it is set
to 3 which is
_IO_FLAG_RD and _IO_FLAG_WR

Regards.

If the iofunc_attr_t refers to a directory (EISDIR after all). A user
cannot directly write to a directory. This is just a sanity check, as
iofunc_open() should have forbid the user from setting up a writable fd
to a directory in the first place (should have returned EISDIR from
there too, so if your resource manager allowed/ignored this then it is
not handling the open() message properly).
