// A TParser is a class for parsing input and formatting it (presumabyl for
|
||
|
|
// display on the screen). All parsers are derived from the TParser class,
|
||
|
|
// in order to facilitate extending telnet to include other kinds of
|
||
|
|
// output. Currently, only one parser is implemented, the ANSI parser.
|
||
|
|
// A TParser includes:
|
||
|
|
// - A ParseBuffer function, which takes as parameters start and end
|
||
|
|
// pointers. It returns a pointer to the last character parsed plus 1.
|
||
|
|
// The start pointer is the beginning of the buffer, and the end
|
||
|
|
// pointer is one character after the end of the buffer.
|
||
|
|
// - An Init() function, which will re-initialize the parser when
|
||
|
|
// necessary.
