+ bool "Enable safe version of sprintf()"
+ help
+ Since sprintf() can overflow its buffer, it is common to use
+ snprintf() instead, which knows the buffer size and can avoid
+ overflow. However, this does increase code size slightly (for
+ Thumb-2, about 420 bytes). Enable this option for safety when
+ using sprintf() with data you do not control.
