◆ seekoff()

virtual std::streampos seekoff ( std::streamoff  off,
std::ios_base::seekdir  way,
std::ios_base::openmode  which = std::ios_base::in|std::ios_base::out 
)
inlineprotectedvirtual

Set position pointer to relative position.

Definition at line 59 of file OCountStream.H.

◆ seekpos()

virtual std::streampos seekpos ( std::streampos  pos,
std::ios_base::openmode  which = std::ios_base::in|std::ios_base::out

Set position pointer to absolute position.

For the counter, adjust the count accordingly.

virtual std::streamsize xsputn ( const char *  s,
std::streamsize  n 
)
inlineprotectedvirtual

Put sequence of characters.
