abort - terminate the process abnormally SYNOPSIS
#include <stdlib.h> void abort(void); DESCRIPTION
The abort() function causes abnormal process termination to occur, unless the signal SIGABRT is being caught and the signal handler does not return. The abnormal termination processing includes at least the effect of fclose(3C) on all open streams and message catalogue descriptors, and the default actions defined for SIGABRT. The SIGABRT signal is sent to the calling process as if by means of the raise(3C) function with the argument SIGABRT. The status made available to wait(3C) or waitpid(3C) by abort will be that of a process terminated by the SIGABRT signal. abort will override blocking or ignoring the SIGABRT signal. RETURN VALUES
The abort() function does not return. ERRORS
No errors are defined. USAGE
Catching the signal is intended to provide the application writer with a portable means to abort processing, free from possible interfer- ence from any implementation-provided library functions. If SIGABRT is neither caught nor ignored, and the current directory is writable, a core dump may be produced. ATTRIBUTES

ABORT(3)						     Linux Programmer's Manual							  ABORT(3)

abort - cause abnormal process termination SYNOPSIS
#include <stdlib.h> void abort(void); DESCRIPTION
The abort() first unblocks the SIGABRT signal, and then raises that signal for the calling process (as though raise(3) was called). This results in the abnormal termination of the process unless the SIGABRT signal is caught and the signal handler does not return (see longjmp(3)). If the SIGABRT signal is ignored, or caught by a handler that returns, the abort() function will still terminate the process. It does this by restoring the default disposition for SIGABRT and then raising the signal for a second time. RETURN VALUE
The abort() function never returns. ATTRIBUTES
For an explanation of the terms used in this section, see attributes(7). +----------+---------------+---------+ |Interface | Attribute | Value | +----------+---------------+---------+ |abort() | Thread safety | MT-Safe | +----------+---------------+---------+ NOTES
Up until glibc 2.26, if the abort() function caused process termination, all open streams were closed and flushed (as with fclose(3)). However, in some cases this could result in deadlocks and data corruption. Therefore, starting with glibc 2.27, abort() terminates the process without flushing streams. POSIX.1 permits either possible behavior, saying that abort() "may include an attempt to effect fclose() on all open streams". CONFORMING TO
