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,        size_t sz, size_t offset)
};
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.
