iofunc_close_dup_default()

Default handler for _IO_CLOSE messages

Synopsis:

#include <sys/iofunc.h>

int iofunc_close_dup_default( resmgr_context_t *ctp,
                              io_close_t *msg,
                              iofunc_ocb_t *ocb );

Library:

libc

Description:

The iofunc_close_dup_default() function implements default actions for the _IO_CLOSE message. This function can be placed directly into the io_funcs table passed to resmgr_attach(), at the close_dup position.

Note that if your resource manager is using 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.

Returns:

EOK
Successful completion.

Classification:

QNX 6

Safety:
Cancellation point No
Interrupt handler No
Signal handler Yes
Thread Yes
