The result of running etc/update-copyright.py --this-year, fixing all the files whose mode is changed by the script, plus a build with --enable-maintainer-mode --enable-cgen-maint=yes, then checking out */po/*.pot which we don't update frequently. The copy of cgen was with commit d1dd5fcc38ead reverted as that commit breaks building of bfp opcodes files.

@deftypefn Supplemental int snprintf (char *@var{buf}, size_t @var{n}, @
|
|
const char *@var{format}, ...)
|
|
|
|
This function is similar to @code{sprintf}, but it will write to
|
|
@var{buf} at most @code{@var{n}-1} bytes of text, followed by a
|
|
terminating null byte, for a total of @var{n} bytes.
|
|
On error the return value is -1, otherwise it returns the number of
|
|
bytes, not including the terminating null byte, that would have been
|
|
written had @var{n} been sufficiently large, regardless of the actual
|
|
value of @var{n}. Note some pre-C99 system libraries do not implement
|
|
this correctly so users cannot generally rely on the return value if
|
|
the system version of this function is used.
