+ * Posix_MkTemp --
+ *
+ *      POSIX mktemp().  It is implemented via mkstemp() to avoid
+ *      warning about using dangerous mktemp() API - but note that
+ *      it suffers from all mktemp() problems - caller has to use
+ *      O_EXCL when creating file, and retry if file already exists.
+ *
+ * Results:
+ *      NULL    Error
+ *      !NULL   Success (result must be freed by the caller)
+ *
+ * Side effects:
+ *      errno is set on error
