Member Function Documentation

◆ get_pod()

template<typename T >

T Gosu::Reader::get_pod ( ByteOrder bo = BO_DONT_CARE )

Similar to read_pod(T&), but returns the read value instead.

Definition at line 74 of file IO.hpp.

◆ position()

std::size_t Gosu::Reader::position ( ) const

Definition at line 42 of file IO.hpp.

◆ read()

void Gosu::Reader::read	(	void *	dest_buffer,
		std::size_t	length
	)

Referenced by Gosu::Resource::back_writer(), Gosu::Buffer::operator=(), read_pod(), and seek().

◆ read_pod()

template<typename T >

void Gosu::Reader::read_pod	(	T &	t,
		ByteOrder	bo = `BO_DONT_CARE`
	)

Convenience function; equivalent to read(&t, sizeof t).
