Interface Function Definition
^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
This set of attributes specifies a function definition. All explicit attributes
shall be specified. The explicit attributes for this type are:
A value of this type shall be of one of the following variants:
attributes
The attribute value shall be an optional string. If the value is present,
then it shall be the function attributes. On the attributes a
context-sensitive substitution of item variables is performed. A function
attribute is for example the indication that the function does not return
to the caller.
* The value may be a set of attributes. This set of attributes specifies a
function definition. All explicit attributes shall be specified. The explicit
attributes for this type are:
body
The attribute value shall be an optional string. If the value is present,
then it shall be the definition of a static inline function. On the
function definition a context-sensitive substitution of item variables is
performed. If no value is present, then the function is declared as an
external function.
attributes
The attribute value shall be an optional string. If the value is present,
then it shall be the function attributes. On the attributes a
context-sensitive substitution of item variables is performed. A
function attribute is for example the indication that the function does
not return to the caller.
params
The attribute value shall be a list of strings. It shall be the list of
parameter declarations of the function. On the function parameter
declarations a context-sensitive substitution of item variables is
performed.
body
The attribute value shall be an optional string. If the value is present,
then it shall be the definition of a static inline function. On the
function definition a context-sensitive substitution of item variables is
performed. If no value is present, then the function is declared as an
external function.
return
The attribute value shall be a string. It shall be the function return
type. On the return type a context-sensitive substitution of item
variables is performed.
params
The attribute value shall be a list of strings. It shall be the list of
parameter declarations of the function. On the function parameter
declarations a context-sensitive substitution of item variables is
performed.
return
The attribute value shall be a string. It shall be the function return
type. On the return type a context-sensitive substitution of item
variables is performed.
* There may by be no value (null).
