# Types of signals

The signals SIGKILL and SIGSTOP may not be caught by a program, and
therefore cannot be affected by this package.

Synchronous signals are signals triggered by errors in program
execution: SIGBUS, SIGFPE, and SIGSEGV. These are only considered
synchronous when caused by program execution, not when sent using
[os.Process.Kill] or the kill program or some similar mechanism. In
