       The  functionality  described  on  this  reference  page is aligned with the ISO C standard. Any conflict
       between the requirements described  here  and  the  ISO C  standard  is  unintentional.  This  volume  of
       POSIX.1‐2017 defers to the ISO C standard.

       The  raise()  function shall send the signal sig to the executing thread or process.  If a signal handler
       is called, the raise() function shall not return until after the signal handler does.

       The effect of the raise() function shall be equivalent to calling:

           pthread_kill(pthread_self(), sig);

       The raise() function shall fail if:

       EINVAL The value of the sig argument is an invalid signal number.

       This  manual  page  is part of the POSIX Programmer's Manual.  The Linux implementation of this interface
       may differ (consult the corresponding Linux manual page for details of Linux behavior), or the  interface
       may not be implemented on Linux.

       The term ``thread'' is an extension to the ISO C standard.

       Upon successful completion, 0 shall be returned. Otherwise, a non-zero value shall be returned and  errno
       shall be set to indicate the error.
