In the C Standard Library, signal processing defines how a program handles various signals while it executes. A signal can report some exceptional behavior within the program (such as division by zero), or a signal can report some asynchronous event outside the program (such as someone striking an interactive attention key on a keyboard).
Signal handlers installed by the signal() interface will be uninstalled immediately prior to execution of the handler. Permanent handlers must therefore be reinstalled by a call to signal() during the handler's execution, causing unreliability in the event a signal of the same type is received during the handler's execution but before the ...
Signal handling is vulnerable to race conditions. As signals are asynchronous, another signal (even of the same type) can be delivered to the process during execution of the signal handling routine. The sigprocmask(2) call can be used to block and unblock delivery of signals. Blocked signals are not delivered to the process until unblocked.

In a POSIX-conformant operating system, a process group denotes a collection of one or more processes. [1] Among other things, a process group is used to control the distribution of a signal; when a signal is directed to a process group, the signal is delivered to each process that is a member of the group.
