Detailed Description

Inputstream for reading files inside a chm archives. 

        chm::chmfile chm("/chmfile.chm");
        chm::chmistream in(chm, "/path");

Constructor & Destructor Documentation

chm::chmistream::chmistream (  const chmfile &    chm,
const std::string &    path,
size_t    buf_size = 1024
) 
 

Create a new input stream from archive for given path.

virtual chm::chmistream::~chmistream (    )  [virtual]
 

Member Function Documentation

unsigned long chm::chmistream::get_dword (    )  [inline]
 

Get local endianized MS dword (2 x 2 bytes) from the stream.

Definition at line 176 of file chmxx.h.

size_t chm::chmistream::get_encint (    )  [inline]
 

Get little endian MS encint from the stream.

Definition at line 160 of file chmxx.h.

unsigned long chm::chmistream::get_sr (  int    s,
int    r,
int &    pos
)  [inline]
 

Get a s-r encoded value from the stream.

Scale must alwqays be 2. Use 0 for initial pos. When finished reading an entry of sr-s call the get_sr_finish(pos).

Definition at line 213 of file chmxx.h.

void chm::chmistream::get_sr_finish (  int &    pos )  [inline]
 

Definition at line 253 of file chmxx.h.

unsigned int chm::chmistream::get_word (    )  [inline]
 

Get local endianized MS word (2 bytes) from the stream.

Definition at line 195 of file chmxx.h.

std::streamsize chm::chmistream::read_left (    ) 
 

Returns the number of bytes that are left to be read from this stream.

So returns the size of file when nothing has been read.
