marshal.h now provides a macro put_fmt() which allows you to write arbitrary printf-formatted data to an arbitrary BinarySink. We already had this facility for strbufs in particular, in the form of strbuf_catf(). That was able to take advantage of knowing the inner structure of a strbuf to minimise memory allocation (it would snprintf directly into the strbuf's existing buffer if possible). For a general black-box BinarySink we can't do that, so instead we dupvprintf into a temporary buffer. For consistency, I've removed strbuf_catf, and converted all uses of it into the new put_fmt - and I've also added an extra vtable method in the BinarySink API, so that put_fmt can still use strbuf_catf's more efficient memory management when talking to a strbuf, and fall back to the simpler strategy when that's not available.
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/>.

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.
