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 );
- A pointer to a resmgr_context_t structure that the resource-manager library uses to pass context information between functions.
- A pointer to the iofunc_ocb_t structure for the Open Control Block that was created when the client opened the resource.
- 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 This means that at least the iofunc_ocb_t portion of your OCB is no longer valid after iofunc_close_ocb() returns.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.
