returns an errno. Note that not all input and output structure members are relevant for
this function.
Returns: The status via the helper macro _IO_SET_CONNECT_RET.
io_openfd()
int io_openfd (resmgr_context_t *ctp, io_openfd_t *msg,
RESMGR_OCB_T *ocb)
Classification: I/O
Default handler: iofunc_openfd_default()
Helper functions: iofunc_openfd()
Client function: openfd()
Messages: _IO_OPENFD

} io_openfd_t;
Description: This function is similar to the handler provided for io_open(), except that
instead of a pathname, an already-open file descriptor is passed (by virtue of passing
you the ocb in the function call).
Returns: The status via the helper macro _RESMGR_STATUS.
io_pathconf()
int io_pathconf (resmgr_context_t *ctp, io_pathconf_t *msg,
RESMGR_OCB_T *ocb)
Classification: I/O
Default handler: iofunc_pathconf_default()
Helper functions: iofunc_pathconf()
Client functions: fpathconf(), pathconf()
Messages: _IO_PATHCONF
