CUnion


is a symbolic representation of a union.

CUnion[name]
declares a union without specifying the contents.

CUnion[None, members]
does not give the union a name.

DetailsDetails

  • SymbolicC expressions are inert; they evaluate to themselves, staying in an unevaluated form.
  • SymbolicC expressions can be converted into a C string with ToCCodeString.
  • The members of the union can be specified with lists or with CDeclare.

This creates a union:

In[2]:=
Click for copyable input
Out[2]=

You can use CDeclare to declare the members of the union:

In[3]:=
Click for copyable input
Out[3]=

You can drop the name for the union by using a specification of None:

In[4]:=
Click for copyable input
Out[4]=

You can use an incomplete type with a typedef:

In[5]:=
Click for copyable input
Out[5]=

You can nest a union inside a struct:

In[6]:=
