iofunc_close_ocb_default()

Return the memory allocated for an OCB

Synopsis:

#include <sys/iofunc.h>

int iofunc_close_ocb_default( resmgr_context_t* ctp,
                              void* reserved,
                              iofunc_ocb_t* ocb );

Library:

libc

Description:

The iofunc_close_ocb_default() function detaches the OCB specified by ocb, and releases the memory associated with it. This function can be placed directly into the io_funcs table passed to resmgr_attach(), at the close_ocb position.

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 This means that at least the iofunc_ocb_t portion of your OCB is no longer valid after iofunc_close_ocb() returns.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

The reserved parameter must be passed as NULL.

Returns:

EOK

Success.

Classification:

QNX 6
