What is the effect of the cobegin and coned
statement in the following code?
var
a,b,c,d,e,f,g : semaphore;
begin
cobegin
begin S1; V(a) ; V(b) end;
begin P(a); s2; V(c); V(d) end;
begin P(b); $3; V(e) end;
begin P(c); P(E); $4 end;
begin P(d); P(0); P(g); S5 end
begin S6; V(£) ; V(g) end;
coend
end:
Select one:
O A It allows for all concurrent execution of the
statements S1, S2 and S3.
O B. It ensures mutual exclusion is imposed.
