246 246 Above AST(\ref{fig:tree2}) is made by syntax of \verb+__code csA(__rectype *p)+ .
247 247 TREE_LIST have infomation of argument.
248 248 First TREE_LIST represent that argument is function pointer(\verb+__code (*p)()+) .
249 249 Second TREE_LIST represent that csA is Fixed-length argument.
250 It is the same as the following. 250 First TREE_LIST is connected with POINTER_TYPE.
251 251 POINTER_TYPE have pointer of function(FUNCTION_TYPE).
252 void csA( void (*p)(void*)) { 252 We have to override it in the pointer of csA.
253 p(csB); 253
