abort(3)
NAME
  abort - Generates a software signal to end the current process

SYNOPSIS
  #include <stdlib.h>

  void abort(
	  void );

LIBRARY
  Standard C Library (libc)

STANDARDS
  Interfaces documented on this reference page conform to industry standards
  as follows:

  abort():  ISO C, POSIX.1, XPG4, XPG4-UNIX

  Refer to the standards(5) reference page for more information about
  industry standards and associated tags.

DESCRIPTION
  The abort() function sends a SIGABRT signal to the current process. This
  signal terminates the process unless both of the following conditions are
  true: (1) signal SIGABRT is being caught, and (2) the signal handler does
  not do a normal return, for example, if it does a longjmp.

  If abort() causes the process to terminate abnormally and the current
  directory is writable, the system creates a core file in the current
  working directory.

  If the call to the abort() function terminates the process, each open
  stream and message catalog descriptor is affected as if the fclose()
  function was called. The abort() function then terminates the process with
  the same result as the _exit() function, with the exception of the status
  value made available to the wait() or waitpid() function. These functions
  receive the status value of the process terminated by the SIGABRT signal.
  The abort() function overrides blocking or ignoring of the SIGABRT signal.

NOTES
  The abort() function is supported for multi-threaded applications.
