<search.h>(P)						     POSIX Programmer's Manual						     <search.h>(P)

NAME

       search.h - search tables

SYNOPSIS

       #include <search.h>

DESCRIPTION

       The <search.h> header shall define the ENTRY type for structure entry which shall include the following members:

	      char    *key
	      void    *data

       and shall define ACTION and VISIT as enumeration data types through type definitions as follows:

	      enum { FIND, ENTER } ACTION;
	      enum { preorder, postorder, endorder, leaf } VISIT;

       The size_t type shall be defined as described in <sys/types.h> .

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

	      int    hcreate(size_t);
	      void   hdestroy(void);
	      ENTRY *hsearch(ENTRY, ACTION);
	      void   insque(void *, void *);
	      void  *lfind(const void *, const void *, size_t *,
			size_t, int (*)(const void *, const void *));
	      void  *lsearch(const void *, void *, size_t *,
			size_t, int (*)(const void *, const void *));
	      void   remque(void *);
	      void  *tdelete(const void *restrict, void **restrict,
			int(*)(const void *, const void *));
	      void  *tfind(const void *, void *const *,
			int(*)(const void *, const void *));
	      void  *tsearch(const void *, void **,
			int(*)(const void *, const void *));
	      void   twalk(const void *,
			void (*)(const void *, VISIT, int ));

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);

       The following sections are informative.

APPLICATION USAGE

       None.

RATIONALE

       None.

FUTURE DIRECTIONS

       None.
