3.3.4 Conversion To and From Strings
When the Esterel C code is generated for interactive simulation, objects of
arbitrary types must be printed by the simulators and possibly entered as
input signal values. For this, the user must define a string representation for
each user-defined type and provide three conversion functions: a function
that converts an object into a string for printing, a function that converts a
string to an object for reading, and a function that checks the syntax of a
string to be read.
The printing function for type T must be called T to text. It must take
a type T object as argument and returns a pointer to characters.
The reading function for type T must be called text to T and it must
return void. It must take as arguments a pointer to characters and a pointer
to T. The function must convert a string into a T object by performing sideeffects
on its pointer argument, the T object being allocated in the generated
code.
The checking function must be called check TYPE. It must take a pointer
to character as argument and return an int. The function must returns 0
if the string is not valid, i.e. if the string is not accepted by the text to T
conversion function as a T object representation.
For example, if the Esterel program uses a type TIME declared as a
C struct compound of three integer fields called hours, minutes, and
seconds, the conversion functions could be defined as:
