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