MadCrowLib is a library of stand alone header files that provide macros for common data structures in C.
"mad crow" because it sounds a bit like "macro"
You can override the memory allocators used with:
#define MC_CALLOC calloc2
#define MC_REALLOC realloc2
Define a buffer with functions to alloc, resize, add, append, reset etc.
Example:
#include "madcrow_buffer.h"
madcrow_buffer_create(charbuf,String,char)
Creates:
typedef struct {
char *data;
size_t len, capacity;
} String;
void charbuf_alloc (String *buf, size_t capacity)
void charbuf_dealloc (String *buf)
void charbuf_reset (String *buf)
void charbuf_capacity (String *buf, size_t capacity)
size_t charbuf_add (String *buf, char obj)
ssize_t charbuf_attempt_add (String *buf, char obj)
void charbuf_append (String *buf, char *obj, size_t n)
void charbuf_shift_left (String *buf, size_t n)
void charbuf_shift_right (String *buf, size_t n)
We also provide general macros to create an empty (unallocated) buffer, and a macro to verify that a buffer is a valid structure:
String string = madcrow_buffer_init;
madcrow_buffer_verify(&string);
Define a list with functions to alloc, reset, push, pop, shift, unshift etc.
Example:
#include "madcrow_list.h"
madcrow_list_create(clist,CharList,char)
Creates:
typedef struct {
char *data;
size_t len, capacity;
} CharList;
void clist_alloc (CharList *buf, size_t capacity)
void clist_dealloc (CharList *buf)
void clist_reset (CharList *buf)
void clist_capacity(CharList *buf, size_t capacity)
size_t clist_push (CharList *buf, char obj)
char clist_pop (CharList *buf)
void clist_popn (CharList *buf, size_t n)
size_t clist_unshift (CharList *buf, char obj)
char clist_shift (CharList *buf)
void clist_shiftn (CharList *buf, size_t n)
char* clist_get (CharList *buf, size_t idx)
size_t clist_length (const CharList *buf)
We also provide general macros to create an empty (unallocated) list, and a macro to verify that a list is a valid structure:
CharList clist = madcrow_list_init;
madcrow_list_verify(&clist);
Define a doubly-linked list with functions to push, pop, shift, unshift etc.
Example:
#include "madcrow_linkedlist.h"
madcrow_linkedlist_create(llist,LinkedList,LinkedNode,char)
Creates:
typedef struct {
char data;
LinkedNode *next, *prev;
} LinkedNode;
typedef struct {
LinkedNode *first, *last;
} LinkedList;
void llist_init (LinkedList *llist)
void llist_push (LinkedList *llist, LinkedNode *obj)
LinkedNode* llist_pop (LinkedList *llist)
void llist_shift (LinkedList *llist, LinkedNode *obj)
LinkedNode* llist_unshift (LinkedList *llist)
size_t llist_length (const LinkedList *llist)
We also provide general macros to create an empty (unallocated) list, and a macro to verify that a linkedlist is a valid structure:
LinkedList llist = madcrow_linkedlist_init;
madcrow_linkedlist_verify(&llist);
TODO:
- [] circular buffer? Or re-write madcrow_list.h as a circular buffer?
