tparser.h

Go to the documentation of this file.

// 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.
