D.2.12.4 compareTasks

Procedure from library tasks.lib (see tasks_lib).

Usage:
compareTasks(t1, t2), t1, t2 tasks

Return:
1, if t1 and t2 coincide;
0, otherwise.

Note:
The arguments and the results of t1 and t2 are not compared.
't1 == t2' is a shortcut for 'compareTasks(t1, t2)'.

Example:
 
LIB "tasks.lib";
ring R = 0, (x,y), dp;
ideal I = x9y2+x10, x2y7-y8;
task t1 = "std", list(I);
task t2 = "std", list(I);
compareTasks(t1, t2);
==> 1
startTasks(t1);
waitAllTasks(t1);
t1 == t2;   // the same as compareTasks(t1, t2);
==> 0
killTask(t1);
killTask(t2);
// The arguments and the result are not compared!
ideal J = x;
task t3 = "std", list(I);
task t4 = "std", list(J);
t3 == t4;
==> 1
killTask(t3);
killTask(t4);
