-/** The signal function associates a "signal handler" with a signal number.
-
- The signal function chooses one of three ways in which receipt of the
- signal number, sig, is to be subsequently handled. If the value of func
- is SIG_DFL, default handling for that signal will occur. If the value of
- func is SIG_IGN, the signal will be ignored. Otherwise, func shall point
- to a function to be called when that signal occurs. An invocation of such a
- function because of a signal, or (recursively) of any further functions
- called by that invocation (other than functions in the standard library),
- is called a signal handler.
-
- At program startup, the equivalent of signal(sig, SIG_IGN); may be executed
- for some signals selected in an implementation-defined manner; the
- equivalent of signal(sig, SIG_DFL); is executed for all other signals
- defined by the implementation.
-
- @return If the request can be honored, the signal function returns the
- value of func for the most recent successful call to signal for
- the specified signal sig. Otherwise, a value of SIG_ERR is
- returned and a positive value is stored in errno.
