An int, zero if OK or nonzero on error. The docs do say this:

The tree traversal continues until one of the following events:
[snipped]
(2)  An invocation of FUNC returns a non-zero value.  In this case,
`__file_tree_walk' stops the tree traversal and returns whatever FUNC
returned.

If you were confused about the prototyping, I refer you to the comp.lang.c FAQ.
