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

       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.1-2008
       defers to the ISO C standard.

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

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

           pptthhrreeaadd__kkiillll((pptthhrreeaadd__sseellff(()),, ssiigg));;

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

EERRRROORRSS
       The _r_a_i_s_e() function shall fail if:

       EEIINNVVAALL The value of the _s_i_g argument is an invalid signal number.
