iofunc_close_ocb()

Return the memory allocated for an OCB

Synopsis:

#include <sys/iofunc.h>

int iofunc_close_ocb( resmgr_context_t* ctp,
                      iofunc_ocb_t* ocb,
                      iofunc_attr_t* attr );

Library:

libc

Description:

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 This means that at least the iofunc_ocb_t portion of your OCB is no longer valid after iofunc_close_ocb() returns.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.

Returns:

EOK

Success.

Classification:

QNX 6
