Changes
Oct-2009 - Defined ZPOS64_T to fpos_t on windows and u_int64_t on linux. (might need to find a better why for this)
Oct-2009 - Change to fseeko64, ftello64 and fopen64 so large files would work on linux.
More if/def section may be needed to support other platforms
Oct-2009 - Defined fxxxx64 calls to normal fopen/ftell/fseek so they would compile on windows.
(but you should use iowin32.c for windows instead)

// skipset.h -- set operations using a skiplist
// Copyright (C) 2024 Mark Adler
// See MiniZip_info.txt for the license.
// This implements a skiplist set, i.e. just keys, no data, with ~O(log n) time
// insert and search operations. The application defines the type of a key, and
// provides a function to compare two keys.
// This header is not definitions of functions found in another source file --
// it creates the set functions, with the application's key type, right where
// the #include is. Before this header is #included, these must be defined:
//
// 1. A macro or typedef for set_key_t, the type of a key.
// 2. A macro or function set_cmp(a, b) to compare two keys. The return values
// are < 0 for a < b, 0 for a == b, and > 0 for a > b.
// 3. A macro or function set_drop(s, k) to release the key k's resources, if
// any, when doing a set_end() or set_clear(). s is a pointer to the set
// that key is in, for use with set_free() if desired.
//
// Example usage:
//
// typedef int set_key_t;
// #define set_cmp(a, b) ((a) < (b) ? -1 : (a) == (b) ? 0 : 1)
// #define set_drop(s, k)
// #include "skipset.h"
//
// int test(void) { // return 0: good, 1: bad, -1: out of memory
// set_t set;
// if (setjmp(set.env))
// return -1;
// set_start(&set);
// set_insert(&set, 2);
// set_insert(&set, 1);
// set_insert(&set, 7);
// int bad = !set_found(&set, 2);
// bad = bad || set_found(&set, 5);
// set_end(&set);
// return bad;
// }
//
// Interface summary (see more details below):
// - set_t is the type of the set being operated on (a set_t pointer is passed)
// - set_start() initializes a new, empty set (initialize set.env first)
// - set_insert() inserts a new key into the set, or not if it's already there
// - set_found() determines whether or not a key is in the set
// - set_end() ends the use of the set, freeing all memory
// - set_clear() empties the set, equivalent to set_end() and then set_start()
// - set_ok() checks if set appears to be usable, i.e. started and not ended
//
// Auxiliary functions available to the application:
// - set_alloc() allocates memory with optional tracking (#define SET_TRACK)
// - set_free() deallocates memory allocated by set_alloc()
// - set_rand() returns 32 random bits (seeded by set_start())

Remove extra information block from a extra information data for the local file header or central directory header

0x0001 is the signature header for the ZIP64 extra information blocks
usage.
