@def PUT_UTF16(val, tmp, PUT_16BIT)
Convert a 32-bit Unicode character to its UTF-16 encoded form (2 or 4 bytes).
@param 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-16. If
val is given as a function it is executed only once.
@param tmp is a temporary variable and should be of type uint16_t. It
represents an intermediate value during conversion that is to be
output by PUT_16BIT.
@param PUT_16BIT writes the converted UTF-16 data to any proper destination
in desired endianness. 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 1 or 2 times depending on input character.

- AV_NE
auto AV_NE(T0 be, T1 le)
@file
common internal and external API header
- FFABS
auto FFABS(T a)
Absolute value, Note, INT_MIN / INT64_MIN result in undefined behavior as they
are not representable as absolute values of their type. This is the same
as with *abs()
@see FFNABS()
- FFDIFFSIGN
auto FFDIFFSIGN(T0 x, T1 y)
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.
- FFMAX

- FFNABS
auto FFNABS(T a)
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.
