Code a C program using a doubly linked list for removing and add a free_list

#include #include #include #include #include "malloc.h"

typedef struct { union { unsigned free : 1; size_t size_dirty; }; } header_t;

typedef struct free_header_t { union { unsigned free : 1; size_t size_dirty; }; struct free_header_t* prev_free; struct free_header_t* next_free; } free_header_t;

typedef header_t footer_t;

typedef struct { header_t* head; free_header_t* first_free_block; void* brk; } params_t;

static params_t params = { NULL, NULL };

static void remove_from_free_list(free_header_t* h); static void add_to_free_list(free_header_t* h); static void check_consistency ();

static void add_to_free_list(free_header_t* h) {

}

}
