Re: [Pharo-users] UFFI can not generate Structure accessor of type char[100]

      it never could. 
you need to do a âspecial typeâ, who has to be something like: 

YourStruct class>>initialize
	Char100 := FFITypeArray ofType: #char.

fieldsDesc
	^ #( 
	Char100 data;
	int count;
	)

but thenâ¦ you want to optimise that and in field accessors, who will look something like this: 

YourStruct >>data
	"This method was automatically generated"
	^(FFITypeArray ofType: #char size: 100) fromHandle: (handle copyFrom: 1 to: 100)

you can change that for: 

YourStruct >>data
	"This method was automatically generated"
	^Char100 fromHandle: (handle copyFrom: 1 to: 100)

and same for setter. 
(other way will work, but it will be suboptimal)

if I try to do
EphCPPTestStructure rebuildFieldAccessors .
in order to generate the accessors for the members of the struct it complains with an error that it does not recognise the type of " [ "
Does that mean that char arrays are other arrays are not supported as struct members or will I have to do this manually ?
