Negative Absolute value.
this works for all integers of all types. As with many macros, this evaluates its argument twice, it thus must not have a sideeffect, that is FFNABS(x++) has undefined behavior.

Comparator.
For two numerical expressions x and y, gives 1 if x > y, -1 if x < y, and 0 if x == y. This is useful for instance in a qsort comparator callback. Furthermore, compilers are able to optimize this to branchless code, and there is no risk of overflow with signed types. As with many macros, this evaluates its argument multiple times, it thus must not have a side-effect.

Convert a 32-bit Unicode character to its UTF-8 encoded form (up to 4 bytes long).
| val | is an input-only argument and should be of type uint32_t. It holds a UCS-4 encoded Unicode character that is to be converted to UTF-8. If val is given as a function it is executed only once. |
| tmp | is a temporary variable and should be of type uint8_t. It represents an intermediate value during conversion that is to be output by PUT_BYTE. |
| PUT_BYTE | writes the converted UTF-8 bytes to any proper destination. It could be a function or a statement, and uses tmp as the input byte. For example, PUT_BYTE could be "*output++ = tmp;" PUT_BYTE will be executed up to 4 times for values in the valid UTF-8 range and up to 7 times in the general case, depending on the length of the converted Unicode character. |
