I have seen many references to blue paint in this newsgroup. Something to do with self-referencing macros, I think. I recently obtained a copy of the ANSI-C standard, and one of the first things I looked for was, of course, blue paint. I could find no mention of it. Can someone explain blue paint? Is it in the standard? If so, where? If not, where did it come from, and where did it go? -- Tom Tkacik tkacik@kyzyl.mi.org Speaking only for myself here in Royal Oak.

"Blue paint" is a standard informal term used in the macro business to indicate that some sort of marker is attached to an object for the sole purpose of being able to tell later that the object has been processed in a specific way. The etymology is unimportant (it probably has something to do with blue coconuts). Section 3.8.3.4 of the C standard is where it is specified that blue paint persists; however, other wording is employed.
