way. For example in parsing C++ there could be a context for code,

one for comments and a third one for preprocessor statements, because

The functions starts to parse with the CurToken() of io_rText.

It leaves io_rText at the first char of the following Token or

the following Context.

This function returns, when a context has parsed some characterss
|
|
and completed a token OR left the context.
|
|
If the token is to be ignored, PassNewToken() returns false
|
|
and cuts the token from io_rText.

|
If the token is to be parsed further in a different context,
|
|
PassNewToken() returns false, but the token is
|
|
NOT cut from io_rText.
|
|
|
|
If the function has found a valid and complete token, PassNewToken()
|
|
passes the parsed token to the internally known receiver and
|

returns true. The token is cut from io_rText.
