Definition:
|
bool b = try_cs(integer cs)
|
|
Description:
|
As enter_cs, but yields false (0) if the lock cannot be obtained instantly.
|
|
pwa/p2js:
|
Not supported.
|
|
Comments:
|
Unlike enter_cs, a prevously declared (user-defined) critical section
must be specified, since the hidden internal stdcs should not be used when expecting
even the slightest lock contention.
|
|
Example:
|
while try_cs(mycs)=0 do
trySomethingElse()
end while
...
leave_cs(mycs)
|
|
Implementation:
|
via :%pTryCS in builtins\VM\pHeap.e (an autoinclude).
