Integral types are the FLI types that represent integers. They consist of the following: :int, :byte, :long, :short, :signed, :unsigned and :enum, along with integer types converting to types with particular sizes defined by ISO C99 such as :int8, :uint64 and :intmax.
Integral types can be combined in a list for readability and compatibility purposes with the foreign language, although when translated to Lisp such combinations are usually returned as a Lisp
integer
, or a
fixnum
for byte sized combinations. For example, a C
unsigned long
can be represented in the FLI as an
(:unsigned :long)
.
