search.h(0P) POSIX Programmer's Manual search.h(0P)
This manual page is part of the POSIX Programmer's Manual. The Linux
implementation of this interface may differ (consult the
corresponding Linux manual page for details of Linux behavior), or
the interface may not be implemented on Linux.
search.h — search tables
#include <search.h>
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 <search.h> header shall define the size_t type 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 ));
