Default handler for _IO_CLOSE messages
#include <sys/iofunc.h> int iofunc_close_dup_default( resmgr_context_t *ctp, io_close_t *msg, iofunc_ocb_t *ocb );
- A pointer to a resmgr_context_t structure that the resource-manager library uses to pass context information between functions.
- A pointer to the io_close_t structure that contains the message that the resource manager received. For more information, see the documentation for iofunc_close_dup().
- 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_close_dup_default() function implements default actions for the _IO_CLOSE message. This function simply calls iofunc_close_dup() to do the actual work.
You can place iofunc_close_dup_default() directly into the io_funcs table passed to resmgr_attach(), at the close_dup position, or you can call iofunc_func_init() to initialize all of the functions to their default values.
If your resource manager uses iofunc_lock_default(), you must use both iofunc_close_dup_default() and iofunc_unblock_default() in their respective handlers, as they provide necessary ancillary functionality for managing file locks. This is because file locks are owned by the process, and aren't inherited by the child process.
- Successful completion.
