ctags uses the following file:

1. It can be difficult to recognize a function definition in C source code. Because
ctags does not know which C preprocessor symbols are defined, there may be
some misplaced function definition information if sections of code within
#if...#endif are not complete blocks.
2. ctags invokes the sort internally.
3. ctags makes special provision for the main() function, which may occur in
several C source files. The tags file contains an entry for the first main() routine
found. For all occurrences of main(), including the first, the tags file contains an
entry for Mname, where name is the name of the input source file, with the .c
suffix and any leading pathname components removed. For example, a tags file
created for a C source code file named foo.c would contain an entry for Mfoo,
which represents the main() routine in foo.c).
4. ctags uses sort to sort the file by tag name, according to the POSIX locale’s
collation sequence.
