    NAME

    ucontext.h - user context
 

    SYNOPSIS

    #include <ucontext.h>  

    DESCRIPTION

    The <ucontext.h> header shall define the mcontext_t type through typedef.

    The <ucontext.h> header shall define the ucontext_t type as a structure that shall include at least the following members: 

    
ucontext_t *uc_link     Pointer to the context that is resumed 
                        when this context returns. 
sigset_t    uc_sigmask  The set of signals that are blocked when this 
                        context is active. 
stack_t     uc_stack    The stack used by this context. 
mcontext_t  uc_mcontext A machine-specific representation of the saved 
                        context.

    The types sigset_t and stack_t shall be defined as in <signal.h> .

    The following shall be declared as functions and may also be defined as macros, Function prototypes shall be provided. 

    
int  getcontext(ucontext_t *);
int  setcontext(const ucontext_t *);
void makecontext(ucontext_t *, void (*)(void), int, ...);
int  swapcontext(ucontext_t *restrict, const ucontext_t *restrict);
