Psigreturn(2)             Oct. 1, 1991              Psigreturn(2)



NAME
     Psigreturn - exit from a signal handler

SYNOPSIS
     void Psigreturn();

DESCRIPTION
     Psigreturn is used to prepare to exit from a signal handler.
     This  is  done  automatically  by  the  kernel when a signal
     handler returns, so it is needed only before a program  uses
     the  C  longjmp  function (or some similar facility) to do a
     non-local jump.  Psigreturn will  fail  (harmlessly)  if  no
     signal is being processed at the time it is called.

     Note that the MiNT library longjmp function already contains
     a  call  to  Psigreturn, so if you're using that library you
     don't need to worry about this.

BUGS
     Calling Psigreturn from a signal handler, and then  actually
     returning  from that handler, is likely to produce extremely
     unpleasant results.
