Spotted by Coverity: if you _just_ gave a filename to bidi_test,
without any previous argument that set testfn to something other than
NULL, the program would crash rather than giving an error message.
(It's only a test program, but test programs you only run once in a
blue moon are the ones that _most_ need to explain their command-line
syntax to you carefully, because you've forgotten it since last time
you used them!)
Also, conditionalised a memcpy on the size not being 0, because it's
illegal to pass a null pointer to memcpy _even_ if size==0. (That
would only happen with a test case containing a zero-length string,
but whatever.)
This is the README for PuTTY, a free Windows and Unix Telnet and SSH
client.
PuTTY is built using CMake <https://cmake.org/>. To compile in the
simplest way (on any of Linux, Windows or Mac), run these commands in
the source directory:
cmake .
cmake --build .
Documentation (in various formats including Windows Help and Unix
`man' pages) is built from the Halibut (`.but') files in the `doc'
subdirectory using `doc/Makefile'. If you aren't using one of our
source snapshots, you'll need to do this yourself. Halibut can be
found at <https://www.chiark.greenend.org.uk/~sgtatham/halibut/>.
The PuTTY home web site is

If you want to send bug reports or feature requests, please read the
Feedback section of the web site before doing so. Sending one-line
reports saying `it doesn't work' will waste your time as much as
ours.
