- Parameters
-
pos An offset relative to the beginning of the stream.
- Returns
- The new position in the stream.

way
)
const
inline
Seeks to the specified write position.
- Parameters
-
off An offset relative to the beginning, current write position, or the end of the stream.
way The starting point (beginning, current, end) for the seek.
- Returns
- The new position in the stream.
template<typename CharType>
Get the underlying stream buffer.
- Returns
- The underlying stream buffer.
template<typename CharType>
Get the current write position, i.e. the offset from the beginning of the stream.
- Returns
- The current write position.
template<typename CharType>
Put a single character into the stream.
- Parameters
-
ch A character
template<typename CharType>
template<typename T >
Write a single value of "blittable" type T into the stream.
- Parameters
-
value A value of type T.
This is not a replacement for a proper binary serialization solution, but it may form the foundation for one. Writing data bit-wise to a stream is a primitive operation of binary serialization. Currently, no attention is paid to byte order. All data is written in the platform's native byte order, which means little-endian on all platforms that have been tested. This function is only available for streams using a single-byte character size.
template<typename CharType>
size_t
count
)
const
inline
Write a number of characters from a given stream buffer into the stream.
- Parameters
-
source A source stream buffer.
count The number of characters to write.
