Interface

Destructor

/* virtual */ ~os_protocol()

Destroys the protocol adapter.

clear

/* virtual */ void clear()

Resets the state of the device adapter for this protocol to good.

device

/* virtual */ const os_adapter& device() const

Returns a constant reference to the device adapter.

device

/* virtual */ void device( const os_adapter& adapter )

Sets the device adapter for this protocol to adapter .

eof

/* virtual */ bool eof() const

Returns true if the device adapter for this protocol has reached end of input.

good

/* virtual */ bool good() const

Returns true if the device adapter for this protocol is in a good state and not at EOF.

/* virtual */ bool ok() const

Returns true if the device adapter for this protocol is in a good state.

read

/* virtual */ bool read( type_t type , void* addr )

Reads the primitive type into the location specified by addr . Returns the number of bytes read.

read_array

/* virtual */ ssize_t read_array( type_t type , void* addr , size_t n )

Reads an array of n primitive type elements into the location specified by addr and returns the number of elements read. With some protocols, this operation can be more efficient than reading each individual element.

reset

/* virtual */ void reset()

Resets the protocol state.

size

/* static */ int size( os_protocol::type_t type ) const

Returns the number of bytes required to store type .

sync

/* virtual */ bool sync()

Flushes all buffered data to the device adapter.

write

/* virtual */ bool write( type_t type , const void* addr )

Writes the primitive type from the location specified by addr . Returns the number of bytes written.

write_array

/* virtual */ ssize_t write_array( type_t type , const void* addr , size_t n )

Writes an array of n primitive type elements from the location specified by addr and returns the number of elements written. With some protocols, this operation can be more efficient than writing each individual element.
