Synopsis:

#include <sys/iofunc.h>

int iofunc_ocb_attach( 
        resmgr_context_t * ctp,
        io_open_t * msg,
        iofunc_ocb_t * ocb,
        iofunc_attr_t * attr,
        const resmgr_io_funcs_t * io_funcs );

Library:

libc

Description:

The iofunc_ocb_attach() function examines the mode specified by the io_open msg, and increments the read and write count flags (ocb->attr->rcount and ocb->attr->wcount), and the locking flags (ocb->attr->rlocks and ocb->attr->wlocks), as specified by the open mode.

This function is called by iofunc_open_default() as part of its initialization.

This function allocates the memory for the OCB if you pass NULL as the ocb.

Returns:

EOK

Successful completion.
