Default handler for _IO_CONNECT messages
#include <sys/iofunc.h> int iofunc_open_default( resmgr_context_t *ctp, io_open_t *msg, iofunc_attr_t *attr, void *extra );

Use the -l c option to qcc to link against this library. This library is usually included automatically.
The iofunc_open_default() function implements the default actions for the _IO_CONNECT message in a resource manager. This function calls:
You can place this function directly into the connect_funcs table passed to resmgr_attach(), at the open position, or you can call iofunc_func_init() to initialize all of the functions to their default values.
See the “Examples” section in the description of iofunc_open() for the skeleton outline of the functionality (the second example, where resmgr_attach() doesn't specify that the managed resource is a directory).
