Default handler for the lock_ocb callout
#include <sys/iofunc.h> int iofunc_lock_ocb_default( resmgr_context_t *ctp, void *reserved, iofunc_ocb_t *ocb );
- A pointer to a resmgr_context_t structure that the resource-manager library uses to pass context information between functions.
- This argument must be NULL.
- A pointer to the iofunc_ocb_t structure for the Open Control Block that was created when the client opened the resource.
Use the -l c option to qcc to link against this library. This library is usually included automatically.
The iofunc_lock_ocb_default() function calls iofunc_attr_lock() to enforce locking on the attributes for the group of messages that were sent by the client.
You can place this function directly into the io_funcs table passed to resmgr_attach() , at the lock_ocb position, or you can call iofunc_func_init() to initialize all of the functions to their default values.
- On the first use, all kernel mutex objects were in use.
