Data Fields

union { 
 
   ssize_t(*   read )(void *obj, void *buf, size_t sz) 
 
   ssize_t(*   read_offs )(void *obj, void *buf, size_t
      sz, size_t offset) 
 
};  
 
union { 
 
   ssize_t(*   write )(void *obj, const void *buf,
       size_t sz) 
 
   ssize_t(*   write_offs )(void *obj, const void *buf,

};  
 
int(* close )(void *obj)
 
int(* ioctl )(void *obj, unsigned int request, va_list args)
 

Detailed Description

File descriptor virtual method table.

Currently all operations beyond read/write/close go thru ioctl method.
