Unblock OCBs

Synopsis:

#include <sys/iofunc.h>

int iofunc_unblock( resmgr_context_t * ctp,
                    iofunc_attr_t * attr );

Since:

BlackBerry 10.0.0

Arguments:

ctp
A pointer to a resmgr_context_t structure that the resource-manager library uses to pass context information between functions.
attr
A pointer to the iofunc_attr_t structure that describes the characteristics of the device that's associated with your resource manager.

Library:

libc

Use the -l c option to qcc to link against this library. This library is usually included automatically.

Description:

The iofunc_unblock() function unblocks any clients that are blocked on any internal resource manager structures.

Currently, this involves only the advisory lock list that's maintained by the attribute.

If a client connection is found:

  • that client is unblocked, and is replied to with the error EINTR.
  • iofunc_unblock() returns _RESMGR_NOREPLY.

If no client connection is found, iofunc_unblock() returns _RESMGR_DEFAULT.

Returns:

_RESMGR_DEFAULT
No client connection was found.
_RESMGR_NOREPLY
A client connection has been unblocked.
