check.signal {AnalysisPageServer} | R Documentation |
Check if an expression results in a signal being delivered
check.signal(expr, signo, testname, no.signal = FALSE)
expr |
The expression to evaluate |
signo |
The signal number (consider using constants like SIGUSR1 from the tools package). |
testname |
Name for this test. Default is to build from signo argument. |
no.signal |
Logical, to invert the sense of the test. Default, FALSE, means to test that the signal was delivered. TRUE means to test that the signal was not delivered. |
Check if an expression results in a signal being delivered. The signal will be caught: you can safely deliver a signal such as SIGUSR1 that would normally cause the process to die.
The value of the evaluated expression, invisibly, so you can do more testing if desired.
