3.7.14 Unnamed fields
When embedding a structure or union within another structure or union, you do not have
to name the internal structure. You can access the contents of the unnamed structure
without using .name to reference it.
Unnamed fields are the same as anonymous unions and structures.
Mode
Supported in GNU mode for C90 and C99 only.
Example
struct
{
int a;
union
{
int b;
float c;
};
int d;
} Unnamed_Fields_0;
int Unnamed_Fields_1()
{
return Unnamed_Fields_0.b;
}
