From 3fbc79ce6f249c527f63763c02ea384e51180f99 Mon Sep 17 00:00:00 2001 From: Kaz Kylheku Date: Sat, 20 May 2017 21:38:50 -0700 Subject: ffi: add two tests based on realpath. The realpath function is called using FFI. One approach passes a null pointer, so that the function dynamically allocates. The return value is str-d, causing FFI to take ownership of the pointer, freeing it. The other approach is to pass a pointer to a large null-terminated character array, marked for ownership transfer to the function. FFI allocates it and puts the argument into it, which is just a dummy empty string. The function fills that buffer and returns it. The return is captured as a str-d, so FFI takes ownership back, and frees the buffer. * tests/017/realpath.tl: New function. * tests/017/realpath.expected: Likewise. --- tests/017/realpath.expected | 2 ++ tests/017/realpath.tl | 12 ++++++++++++ 2 files changed, 14 insertions(+) create mode 100644 tests/017/realpath.expected create mode 100644 tests/017/realpath.tl (limited to 'tests/017') diff --git a/tests/017/realpath.expected b/tests/017/realpath.expected new file mode 100644 index 00000000..659aa110 --- /dev/null +++ b/tests/017/realpath.expected @@ -0,0 +1,2 @@ +"/usr/bin" +"/usr/bin" diff --git a/tests/017/realpath.tl b/tests/017/realpath.tl new file mode 100644 index 00000000..d920825f --- /dev/null +++ b/tests/017/realpath.tl @@ -0,0 +1,12 @@ +(load "../common") + +(with-dyn-lib (libc) + (deffi realpath-null "realpath" str-d (str str)) + (deffi realpath-buf "realpath" str-d (str (ptr-in-d (zarray 8192 char))))) + +(when (memq (os-symbol) '(:cygwin :solaris)) + (put-string (file-get-string "tests/017/realpath.expected")) + (exit 0)) + +(prinl (realpath-null "/usr/bin" nil)) +(prinl (realpath-buf "/usr/bin" (copy ""))) -- cgit v1.2.3
