Constructor & Destructor Documentation

PlainFileReader::PlainFileReader (  int  fd, size_t  bufmax = 4096 )

The PlainFile does not make an assumption whether the file descriptor is blocking or non-blocking. If it is non-blocking without any data to read, it will return an error. The file descriptor is not considered owned by the PlainFile object, ie. it will not be discarded on deletion of the object. However, no implications about the number of read or unread bytes must be made by the calling application. Parameters: fd  file descriptor to read from bufmax  optional size of the dynamically allocated buffer

virtual PlainFileReader::~PlainFileReader (   )  [virtual]

Destructor.

Member Function Documentation

virtual bool PlainFileReader::eof (   )  const [virtual]

If the file descriptor refers to a blocking file, this function can be used by the application to determine whether the end of file has been reached. In case of non-blocking operation, the function is meaningless. Returns: True if the read operation has returned 0 bytes, false otherwise.

int PlainFileReader::fd (   )  const

Retrieves the current file descriptor. Returns: the current file descriptor

int PlainFileReader::getByte (   )  [virtual]

Gets a byte from the given file. Returns: a byte value in the range 0x00 - 0xff or -1 in case of error. Implements PlainReader.
