Constants

• ARITH_MAX
  The max value that will be added or subtracted during add mutations
• INTERESTING_8
  Interesting 8-bit values from AFL
• INTERESTING_16
  Interesting 16-bit values from AFL
• INTERESTING_32
  Interesting 32-bit values from AFL

Functions

• buffer_set
  A simple way to set buffer contents. The compiler does the heavy lifting. see https://stackoverflow.com/a/51732799/1345238/
• rand_range
  Generate a range of values where (upon repeated calls) each index is likely to appear in the provided range as likely as any other value
• str_decode
  Decodes a dictionary token: ‘foo\x41\and"bar’ -> ‘fooA\and“bar’
