/* Unlike Programs and Configurations which get mapped onto C++ classes, |
|
53 |
* Function Blocks are mapped onto a C structure containing the variables, and |
|
54 |
* a C function containing the code in the FB's body. This is to allow direct allocation |
|
55 |
* of a FB variable (which is really an instance of the C data structure) to |
|
56 |
* a member of a union variable (note that classes with constructors cannot |
|
57 |
* be mebers of a union), which is done in IL when loading a FB onto IL's |
|
58 |
* default variable. |
|
59 |
* |
|
60 |
* So as not to clash the names of the C data structure and the C function, |
|
61 |
* the C structure is given a name identical to that of the FB name, whereas |
|
62 |
* the name of the function is the FB name with a constant string appended. |
|
63 |
* The value of that constant string which is appended is defined in the following |
|
64 |
* constant. |
|
65 |
* In order not to clash with any variable in the IL and ST source codem the |
|
66 |
* following constant should contain a double underscore, which is not allowed |
|
67 |
* in IL and ST. |
|
68 |

* e.g.: FUNTION_BLOCK TEST |
|
70 |
* is mapped onto a TEST data structure, and a TEST_body__ function. |
