44 FUNCTION
45 <<abort>>---abnormal termination of a program
46 
47 INDEX
48 	abort
49 
50 SYNOPSIS
51 	#include <stdlib.h>
52 	void abort(void);
53 
54 DESCRIPTION
55 Use <<abort>> to signal that your program has detected a condition it
56 cannot deal with.  Normally, <<abort>> ends your program's execution.
57 
58 Before terminating your program, <<abort>> raises the exception <<SIGABRT>>
59 (using `<<raise(SIGABRT)>>').  If you have used <<signal>> to register
60 an exception handler for this condition, that handler has the
61 opportunity to retain control, thereby avoiding program termination.
62 
63 In this implementation, <<abort>> does not perform any stream- or
64 file-related cleanup (the host environment may do so; if not, you can
65 arrange for your program to do its own cleanup with a <<SIGABRT>>
66 exception handler).
67 
68 RETURNS
69 <<abort>> does not return to its caller.
70 
71 PORTABILITY
72 ANSI C requires <<abort>>.
73 
74 Supporting OS subroutines required: <<_exit>> and optionally, <<write>>.
