Detailed Description

This provides a wide character source with lookahead and tracking of source location and indentation. As the name suggests, it's indented to provide input for lexical analyzers, but may be suitable for other textual processing, as well.

Function Documentation

void cutext_locbound_put_wchar ( cu_locbound_t  locb,
cu_wchar_t  ch 

A currently rough approximation to a Unicode version of cu_locbound_put_char.

cu_wchar_t cutext_lsource_get ( cutext_lsource_t  src  ) 

Returns and skips over the next character of src.

cu_wchar_t cutext_lsource_peek ( cutext_lsource_t  src  ) 

Returns the next character from the source, without skipping over it.
