\section{\class{wxDataInputStream}}\label{wxdatainputstream}
This class provides functions that read binary data types in a
-portable way. Data can be read in either big-endian or litte-endian
+portable way. Data can be read in either big-endian or little-endian
format, little-endian being the default on all architectures.
If you want to read data from text files (or streams) use

-If {\it be\_order} is TRUE, all data will be read in big-endian
+If {\it be\_order} is true, all data will be read in big-endian
order, such as written by programs on a big endian architecture
(e.g. Sparc) or written by Java-Streams (which always use
big-endian order).
-\membersection{wxDataInputStream::Read8}

Reads a single byte from the stream.
-\membersection{wxDataInputStream::Read16}
+\func{void}{Read8}{\param{wxUint8 *}{buffer}, \param{size\_t }{size}}
+
+Reads bytes from the stream in a specified buffer. The amount of
+bytes to read is specified by the {\it size} variable.

-\membersection{wxDataInputStream::Read32}
+\func{void}{Read16}{\param{wxUint16 *}{buffer}, \param{size\_t }{size}}
+
+Reads 16 bit unsigned integers from the stream in a specified buffer. the

+\func{void}{Read64}{\param{wxUint64 *}{buffer}, \param{size\_t }{size}}
+
+Reads 64 bit unsigned integers from the stream in a specified buffer. the amount of

+\membersection{wxDataInputStream::ReadDouble}\label{wxdatainputstreamreaddouble}
\func{double}{ReadDouble}{\void}
Reads a double (IEEE encoded) from the stream.
-\membersection{wxDataInputStream::ReadString}
+\func{void}{ReadDouble}{\param{double *}{buffer}, \param{size\_t }{size}}
+
+Reads double data (IEEE encoded) from the stream in a specified buffer. the amount of

+
+\membersection{wxDataInputStream::ReadString}\label{wxdatainputstreamreadstring}
\func{wxString}{ReadString}{\void}
-Reads a string from a stream. Actually, this function first reads a long integer
-specifying the length of the string (without the last null character) and then
-reads the string.
+Reads a string from a stream. Actually, this function first reads a long

+and then reads the string.
+
+In Unicode build of wxWidgets, the fuction first reads multibyte (char*)
+string from the stream and then converts it to Unicode using the {\it conv}
+object passed to constructor and returns the result as wxString. You are
+responsible for using the same convertor as when writing the stream.
