NAME
       abort - generate an abnormal termination signal

SYNOPSIS
       #include <stdlib.h>

       void abort (void);

DESCRIPTION
       abort first closes all open files in standard I/O; then, if possible,
       causes the signal SIGABRT to be sent to the calling process.

DIAGNOSTICS
       If all of these conditions are met, a core dump is produced and the
       shell writes an abort - core dumped message:

       *    SIGABRT is not caught.

       *    The current directory is writable.

       *    The euid and uid are the same.

       *    The RLIMIT_CORE resource limit is set to a non-zero value.
