18 | SYNOPSIS |
---|
19 | #include <stdlib.h> |
---|
20 | void abort(void); |
---|
21 | |
---|
22 | DESCRIPTION |
---|
23 | Use <<abort>> to signal that your program has detected a condition it |
---|
24 | cannot deal with. Normally, <<abort>> ends your program's execution. |
---|
25 | |
---|
26 | Before terminating your program, <<abort>> raises the exception <<SIGABRT>> |
---|
27 | (using `<<raise(SIGABRT)>>'). If you have used <<signal>> to register |
---|
28 | an exception handler for this condition, that handler has the |
---|
29 | opportunity to retain control, thereby avoiding program termination. |
---|
30 | |
---|
31 | In this implementation, <<abort>> does not perform any stream- or |
---|
32 | file-related cleanup (the host environment may do so; if not, you can |
---|
33 | arrange for your program to do its own cleanup with a <<SIGABRT>> |
---|
34 | exception handler). |
---|
35 | |
---|
36 | RETURNS |
---|
37 | <<abort>> does not return to its caller. |
---|
38 | |
---|
39 | PORTABILITY |
---|
40 | ANSI C requires <<abort>>. |
---|
41 | |
---|
42 | Supporting OS subroutines required: <<_exit>> and optionally, <<write>>. |
