Public Member Functions inherited from wxInputStream | |
| wxInputStream () | |
| Creates a dummy input stream. More... | |
| virtual | ~wxInputStream () |
| Destructor. More... | |
| virtual bool | CanRead () const |
| Returns true if some data is available in the stream right now, so that calling Read() wouldn't block. More... | |
| virtual bool | Eof () const |
| Returns true after an attempt has been made to read past the end of the stream. More... | |
| int | GetC () |
| Returns the first character in the input queue and removes it, blocking until it appears if necessary. More... | |
| virtual size_t | LastRead () const |
| Returns the last number of bytes read. More... | |
| virtual char | Peek () |
| Returns the first character in the input queue without removing it. More... | |
| virtual wxInputStream & | Read (void *buffer, size_t size) |
| Reads the specified amount of bytes and stores the data in buffer. More... | |

| Changes the stream current position. More... | |
| virtual wxFileOffset | TellI () const |
| Returns the current stream position or wxInvalidOffset if it's not available (e.g. More... | |
| size_t | Ungetch (const void *buffer, size_t size) |
| This function is only useful in read mode. More... | |
| bool | Ungetch (char c) |
| This function acts like the previous one except that it takes only one character: it is sometimes shorter to use than the generic function. More... | |
