Headers                                         ucontext.h(3HEAD)



NAME
     ucontext.h, ucontext - user context

SYNOPSIS
     #include 


DESCRIPTION
     The   header defines the ucontext_t  type  as  a
     structure that includes at least the following members:

       ucontext_t  uc_link
       sigset_t    uc_sigmask
       stack_t     uc_stack
       mcontext_t  uc_mcontext



     The uc_link member is a pointer to the context to be resumed
     when  this  context  returns. If uc_link is equal to 0, this
     context is the main context and the process exits when  this
     context returns.


     The uc_sigmask member defines the set of  signals  that  are
     blocked when this context is active. See sigprocmask(2).


     The uc_stack member defines the stack used by this  context.
     See sigaltstack(2).


     The uc_mcontext member contains the  saved  set  of  machine
     registers  and  any  implementation-specific  context  data.
     Portable  applications   should   not   modify   or   access
     uc_mcontext.
