Default handler for _IO_OPENFD messages
#include <sys/iofunc.h> int iofunc_openfd_default( resmgr_context_t *ctp, io_openfd_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_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.
