Re: [Ctags] C-tags for Multiple definition of function

[<ga...@ca...>]

Normally, ctags will (only) generate a tag for the definition, and not the
declaration...so if you're only getting a tag for the definition, something is
unusal.

It could also be the "style" of the source code; let me explain.

By default, for functions anyway, ctags uses patterns to identify the location
of a tag (as opposed to a line number) that way if code is added or moved
around, the tag remains valid.

Take the following example:

     // Declaration
     static int foo(int);

     ...

     // Definition
     static int foo(
     int my_arg
     )
     {
	  <function code>
     }

The tag generated for 'foo' will be something like:

     foo     <file>        /^static int foo($/;"   function

Which would match the function definition, and not the declaration.

However, say I had the code like this:

     // Declaration
     static int foo(
     int
     );

     ...

     // Definition
     static int foo(
     int my_arg
     )
     {
	  <function code>
     }

The tag generated for 'foo' would still look the same, but the pattern used to
locate the tag would now also match the function's declaration.

Make sense?

A possible solution to this would be to use the -B option to ctags, which will
generate backward-searching patterns, which would have the effect of locating
the function instead of the prototype, since the prototype comes first in the
file.

| hi gary,
| One more help please..
| It worked well in case of declaration and the
| definition of functions are in  different files but if
| both are in same file then since ctags are generating
| the tags only for first occurance i.e. the declaration
| of function it is not showing the definition of
| function in the match list. Can u please help me in
| getting multiple tags.
