<SIGNAL.H> SIGNAL HANDLING
The header file
specify how the program handles signals while it is executing. A signal is a condition
that may be reported during the program execution. Signals are synchronous, occur-

A signal may be handled by:
• Default handling (
• Ignoring the signal (
• Handling the signal with a function designated via
By default all signals are handled by the default handler, which is identified by

typedef int sig_atomic_t;
Used as the second argument and/or the return value for signal to
specify that the default handler should be used for a specific signal.
<signal.h>
Used as the return value for signal when it cannot complete a
request due to an error.

Used as the second argument and/or the return value for signal to
specify that the signal should be ignored.
