CC Mode 5.32.99 (C/l); `c-defun-name' returns wrong result for filescope enums, structs and unions |
|
Date: |

When the point is in struct, enum or union of file scope, `c-defun-name'
returns wrong result.
Eg: In the following example (where `|' is where the points are (ie, 3
cursors are 3 different cases),
case 1, in struct: the result is "t" ("struct test" may be a better
result, the same for union)
case 2, in enum: the result is "ONE" ("enum" may be better)
case 3, in main: the result is "main" (which is of course, right)
Also, simply return "struct", "union", etc if no tag name is present
(like in "typedef struct {...")
struct test
{
int a;|
};
enum {
ONE,
TWO|
};
int
main (void)
{
|
}

I put on my (hopefully benevolent) dictator's hat and decided to stick
with my reasoning, here.

Thanks. I've committed the patch and closed the bug.

I'm afraid I used my dictator's hat here, too.
Anyway, the bug is, at long last, closed.
