Subject: int → ptrdiff_t for read results
X-Git-Url: http://git.eshelyaron.com/gitweb/?a=commitdiff_plain;h=b36b12887dfa9757054bc2f3e7a43857f015c0c6;p=emacs.git

int → ptrdiff_t for read results

* src/fileio.c (Finsert_file_contents): Use ptrdiff_t, not int, to
store results returned by emacs_fd_read, which return ptrdiff_t.
This doesn’t fix any bugs since the values happen to fit in int,
but is a bit clearer and may simplify future changes.
