UCONTEXT.H(3HEAD)					     UCONTEXT.H(3HEAD)

NAME
       ucontext.h, ucontext - user context

SYNOPSIS
       #include <ucontext.h>

DESCRIPTION
       The   <ucontext.h>  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 that 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 sigalt‐
       stack(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.
