I looped over the toplevel header files, creating a temporary two-line C program for each consisting of #include "git-compat-util.h" #include $HEADER This patch is the result of manually fixing errors in compiling those tiny programs.

* Iterate over a directory tree.

|
|
* Iterate over a directory tree, recursively, including paths of all
|
|
* types and hidden paths. Skip "." and ".." entries and don't follow
|
|
* symlinks except for the original path.
|
|
*
|
|
* Every time dir_iterator_advance() is called, update the members of
|
|
* the dir_iterator structure to reflect the next path in the
|
|
* iteration. The order that paths are iterated over within a
|
|
* directory is undefined, but directory paths are always iterated
|
|
* over before the subdirectory contents.
|
|
*
|
|
* A typical iteration looks like this:
|
|
*
|
|
* int ok;
|
|
* struct iterator *iter = dir_iterator_begin(path);
|
|
*
|
|
* while ((ok = dir_iterator_advance(iter)) == ITER_OK) {
|
|
* if (want_to_stop_iteration()) {
|
|
* ok = dir_iterator_abort(iter);
|
|
* break;
|
|
* }
|
|
*
|
|
* // Access information about the current path:
|
|
* if (S_ISDIR(iter->st.st_mode))
|
|
* printf("%s is a directory\n", iter->relative_path);
|
|
* }
|
|
*
|
|
* if (ok != ITER_DONE)
|
|
* handle_error();
|
|
*
|
|
* Callers are allowed to modify iter->path while they are working,
|
|
* but they must restore it to its original contents before calling
|
|
* dir_iterator_advance() again.
