Description:

The function iofunc_openfd_default() function implements the default actions for _IO_OPENFD messages.

You can place this function directly into the io_funcs table passed to resmgr_attach(), at the openfd position, or you can call iofunc_func_init() to initialize all of the functions to their default values.

The iofunc_openfd_default() function calls iofunc_openfd() to do the actual work.

Returns:

EOK
Success.
EACCES
You don't have permission to open the file.
EBUSY
The file has shared locks that are in use.
EINVAL
The message type is invalid.
