вызвать аварийное завершение процесса (cause abnormal process termination)
Имя (Name)
abort - cause abnormal process termination
Синопсис (Synopsis)
#include <stdlib.h>
noreturn void abort(void);
Описание (Description)
The abort() function 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.
Возвращаемое значение (Return value)
The abort() function never returns.

Примечание (Note)
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".
