+FUNCTION
+<<abort>>---abnormal termination of a program
+
+INDEX
+ abort
+
+ANSI_SYNOPSIS
+ #include <stdlib.h>
+ void abort(void);
+
+TRAD_SYNOPSIS
+ #include <stdlib.h>
+ void abort();
+
+DESCRIPTION
+Use <<abort>> to signal that your program has detected a condition it
+cannot deal with. Normally, <<abort>> ends your program's execution.
+
+Before terminating your program, <<abort>> raises the exception <<SIGABRT>>
+(using `<<raise(SIGABRT)>>'). If you have used <<signal>> to register
+an exception handler for this condition, that handler has the
+opportunity to retain control, thereby avoiding program termination.
+
+In this implementation, <<abort>> does not perform any stream- or
+file-related cleanup (the host environment may do so; if not, you can
+arrange for your program to do its own cleanup with a <<SIGABRT>>
+exception handler).
+
+RETURNS
+<<abort>> does not return to its caller.
+
+PORTABILITY
+ANSI C requires <<abort>>.
+
+Supporting OS subroutines required: <<getpid>>, <<kill>>.
