Description

The API has two key concepts: lexical +analyser, and extraction mark.

+
Lexical analyser

The lexical analyser provides facilities +to identify and extract characters and tokens (substrings delimited by white +space) from a descriptor or NULL-terminated string. It also provides string-to-number +conversions.

The lexical analyser interface is provided by TLex16 for +wide strings, and TLex8 for narrow strings. TLex is +a typedef for TLex16.

+
Extraction mark

The extraction mark allows positions +in a string that is being analysed to be remembered. Later lexical analysis +operations can then operate on this position in the string.

The extraction +mark interface is provided by TLexMark16 for wide strings, +and TLexMark8 for narrow strings. TLexMark is +a typedef for TLexMark16.
