5 description: Enables use of [pseudo] classes. (type of C++ / OOP)
6 compiler: CCS C

9 Notes:
10 This was based on my 1.01 source of class.h
11 I created as pclass, due to large amount of code already
12 written for class.c, so I didnt want to replace it
13
14 Some Pre-Processor fun :)

18 Usage:
19 You must setup a "class name" for your instance;
20
21 ClassDef gpsBuffer
22 ClassInclude "cls_circbuffer.c"
23 ClassEnd
24
25 ClassDef compassBuffer
26 ClassInclude "cls_circbuffer.c"
27 ClassEnd
28
29 To access a function or variable in the above class;
30
31 c = gpsBuffer_getChr();
32 c = compassBuffer_getChr();
33
34
35 In each included class file, all functions must be prefaced
36 with clsFn(), and all global variables with clsVar()
37
38 example source of cls_circbuffer.c:
39
40 char clsVar(buf[256]);
41 unsigned int8 clsVar(bpIn);
42 unsigned int8 clsVar(bpOut);
43
44 char clsFn(getChr(void))
45 {
46 char b;
47 b = clsVar(buf[clsVar(bpOut)]);
48 clsVar(bpOut++);
49 return b;
50 }
