|
* Name: Abort
|
|
*
|
|
* Description:
|
|
* The abort() first unblocks the SIGABRT signal, and then raises that
|
|
* signal for the calling process. This results in the abnormal
|
|
* termination of the process unless the SIGABRT signal is caught and
|
|
* the signal handler does not return.
|
|
*
|
|
* If the abort() function causes process termination, all open
|
|
* streams are closed and flushed.
|
|
*
|
|
* 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.
|
|
*
|
|
* Input Parameters:
|
|
* None
|
|
*
|
|
* Returned Value:
|
|
* This function does not return,
|
|
*
|

void abort(void)
|
|
{
|
|
/* NuttX does not support standard signal functionality (like the
|
|
* behavior of the SIGABRT signal). So no attempt is made to provide
|
|
* a conformant version of abort() at this time. This version does not
|
|
* signal the calling thread all.
|
|
*
|
|
* Note that pthread_exit() is called instead of exit(). That is because
|
|
* we do no know if abort was called from a pthread or a normal thread
|
|
* (we could find out, of course). If abort() is called from a
|
|
* non-pthread, then pthread_exit() should fail and fall back to call
|
|
* exit() anyway.
|
|
*
|
|
* If exit() is called (either below or via pthread_exit()), then exit()
|
|
* will flush and close all open files and terminate the thread. If this
|
|
* function was called from a pthread, then pthread_exit() will complete
|
|
* any joins, but will not flush or close any streams.
