Stateflow User's Guide

Pointer and Address Operations

The address operator is available for use with both custom code variables and Stateflow variables. The pointer operator is available for use with custom code variables only.

Note    The action language parser uses a relaxed set of restrictions. As a result, many syntax errors are not trapped until compilation.

The following examples show syntax that is valid for use with custom code variables only.

• varStruct.field = <expression>;
  (*varPtr) = <expression>;
  varPtr->field = <expression>;
  myVar = varPtr->field;
  varPtrArray[index]->field = <expression>;
  varPtrArray[expression]->field = <expression>;
  myVar = varPtrArray[expression]->field;
  

The following examples show syntax that is valid for use both with custom code variables and with Stateflow variables.

• varPtr = &var;
  ptr = &varArray[<expression>];
  *(&var) = <expression>;
  function(&varA, &varB, &varC);
  function(&sf.varArray[<expression>]);
