157c478bd9Sstevel@tonic-gate * Modify ctags to handle C++ in C_entries(), etc:
167c478bd9Sstevel@tonic-gate * - Handles C++ comment token "//"
177c478bd9Sstevel@tonic-gate * - Handles C++ scope operator "::".
187c478bd9Sstevel@tonic-gate * This helps to distinguish between xyz()
197c478bd9Sstevel@tonic-gate * definition and X::xyz() definition.
207c478bd9Sstevel@tonic-gate * - Recognizes C++ reserved word "class" in typedef processing
217c478bd9Sstevel@tonic-gate * (for "-t" option)
227c478bd9Sstevel@tonic-gate * - Handles Sun C++ special file name extensions: .c, .C, .cc, and .cxx.
237c478bd9Sstevel@tonic-gate * - Handles overloaded unary/binary operator names
247c478bd9Sstevel@tonic-gate * Doesn't handle yet:
257c478bd9Sstevel@tonic-gate * - inline functions in class definition (currently they get
267c478bd9Sstevel@tonic-gate * swallowed within a class definition)
277c478bd9Sstevel@tonic-gate * - Tags with scope operator :: with spaces in between,
287c478bd9Sstevel@tonic-gate * e.g. classz ::afunc
297c478bd9Sstevel@tonic-gate *
307c478bd9Sstevel@tonic-gate * Enhance operator functions support:
319b73ad49SToomas Soome * - Control flow involving operator tokens scanning are
327c478bd9Sstevel@tonic-gate * consistent with that of other function tokens - original
337c478bd9Sstevel@tonic-gate * hacking method for 2.0 is removed. This will accurately
347c478bd9Sstevel@tonic-gate * identify tags for declarations of the form 'operator+()'
357c478bd9Sstevel@tonic-gate * (bugid 1027806) as well as allowing spaces in between
367c478bd9Sstevel@tonic-gate * 'operator' and 'oprtk', e.g. 'operator + ()'.
