Default handler for _IO_SYNC messages
#include <sys/iofunc.h> int iofunc_sync_default( resmgr_context_t *ctp, io_sync_t *msg, iofunc_ocb_t *ocb );
libc
Use the -l c option to qcc to link against this library. This library is usually included automatically.
The function iofunc_sync_default() function implements POSIX semantics for the client's sync() call, which is received as an _IO_SYNC message by the resource manager.
You can place this function directly into the io_funcs table passed to resmgr_attach(), at the sync position, or you can call iofunc_func_init() to initialize all of the functions to their default values.
The iofunc_sync_default() function calls iofunc_sync_verify() to see if the client can synchronize the resource.
