The example for WriteFile assumed the existence of a testdata/ directory, which is not present on the playground. The example now writes the file to the current working directory, rather than to testdata/.

Allow TempDir to create directories with predictable
prefixes and suffixes, separated by the last "*", for example:
"prefix*suffix"
will now expand to
"prefix" + <RANDOM_VALUE> + "suffix"

Users of TempFile need to be able to supply the suffix, especially
when using operating systems that give semantic meaning to the
filename extension such as Windows. Renaming the file to include
an extension after the fact is insufficient as it could lead to
race conditions.
If the string given to TempFile includes a "*", the random string
replaces the "*". For example "myname.*.bat" will result in a random
filename such as "myname.123456.bat". If no "*' is included the
old behavior is retained, and the random digits are appended to the
end.
If multiple "*" are included, the final one is replaced, thus
permitting a pathological programmer to create filenames such as
"foo*.123456.bat" but not "foo.123456.*.bat"
