mscgen

<mscgen caption="Message sequence chart for example no. 4"> msc {

 a,b,c;
 a->b  [label="ab()"];
 b->c  [label="bc(TRUE)"];
 c=>c  [label="process(1)"];
 c=>c  [label="process(2)"];
 ...;
 c=>c  [label="process(n)"];
 c=>c  [label="process(END)"];
 a<<=c [label="callback()"];
 ---   [label="If more to run", ID="*"];
 a->a  [label="next()"];
 a->c  [label="ac()"];
 b<-c  [label="cb(TRUE)"];
