Return the memory allocated for an OCB
#include <sys/iofunc.h>
int iofunc_close_ocb( resmgr_context_t* ctp,
iofunc_ocb_t* ocb,
iofunc_attr_t* attr );
- ctp
- A pointer to a
resmgr_context_t
structure that the resource-manager library uses to pass context information
between functions.
- ocb
- A pointer to the
iofunc_ocb_t
structure for the Open Control Block that was created when the
client opened the resource.
- attr
- A pointer to the
iofunc_attr_t
structure that describes the characteristics of the device that's
associated with your resource manager.

Use the -l c option to
qcc
to link against this library.
This library is usually included automatically.
The iofunc_close_ocb() function detaches the OCB specified
by ocb, and releases the memory associated with it.
|
This function assumes that ocb points to an iofunc_ocb_t.
If you encapsulate iofunc_ocb_t in your own OCB it
must be the first field of your OCB; otherwise, you can't call this function.
If you provide an ocb_free() function in the
mount structure then it's called at this point. This means
that at least the iofunc_ocb_t portion of your OCB is no longer
valid after iofunc_close_ocb() returns. |
The iofunc_close_ocb() function calls
iofunc_ocb_detach()
on your behalf.
- EOK
- Success.
