Описание:

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.


Note: If your resource manager uses iofunc_lock_default(), you must use both this function (iofunc_close_dup_default()) and iofunc_unblock_default(), 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.
