Module signal 

Available on Windows and crate feature signals only.

C signal support on Windows.

A big difference from POSIX platforms is the amount of signals that Windows supports. Signals on Windows are therefore much less useful than POSIX ones.

Signal safe C functions

The C standard specifies that calling any functions other than those ones from a signal hook results in undefined behavior:

• abort
• _Exit
• quick_exit
• signal, but only if it is used for setting a handler for the same signal as the one being currently handled
• atomic C functions, but only the ones which are lock-free (practically never used in Rust since it has its own atomics which use compiler intrinsics)
• atomic_is_lock_free
