Any further actions on the reader should fail.
Implemented in ID3_IStreamReader, ID3_IFStreamReader, and ID3_MemoryReader.
virtual pos_type ID3_Reader::getBeg | ( | ) | [inline, virtual] |

virtual int_type ID3_Reader::readChar | ( | ) | [inline, virtual] |
Read a single character and advance the internal position.
Note that the interal position may advance more than one byte for a single character read. Returns END_OF_READER if there isn't a character to read.
Definition at line 65 of file reader.h.
Referenced by ID3_TagImpl::IsV2Tag(), dami::id3::v1::parse(), and ID3_TagHeader::ParseExtended().
virtual int_type ID3_Reader::peekChar | ( | ) | [pure virtual] |
Return the next character to be read without advancing the internal position.
Returns END_OF_READER if there isn't a character to read.
Implemented in ID3_IStreamReader, and ID3_MemoryReader.
Read up to len
characters into buf and advance the internal position accordingly.
Returns the number of characters read into buf. Note that the value returned may be less than the number of bytes that the internal position advances, due to multi-byte characters.
