C_Darray

Dynamic array implemented in C

Create a new array with INT

DataType dtype = INT;
DArray *arr_int = NULL;
arr_int = darray_create(1024, dtype);

Destory the array

darray_destory(arr_int);

Push value(s)

one at a time

int v = 123;
darray_push(arr_int, v);

vectorized push

int src[] = {1, 2, 3, 4, 5};
int vec_size = 5;
darray_vec_push(arr_int, src, vec_size);

Get by index

int index = 10;
PDataType pres;
arr_int->get(arr_int, index, &pres);
printf("%d\n", *(pres.pint));

DateType and PDataType are defined as:

typedef	enum _dataType {
	CHAR,
	INT,
	LONG,
	FLOAT,
	DOUBLE,
	SIZET
} DataType;

typedef union _pdatatype {
	char *pchar;
	int *pint;
	long *plong;
	float *pfloat;
	double *pdouble;
	size_t *psizet;
} PDataType;

Generic and specific type array are defined as:

#define _darray_type_declare(T) \
	struct _darray_struct_##T { \
		const size_t element_size; \
		size_t capacity; \
		size_t length; \
		T *content; \
		void (* const get)(DArray *, size_t, PDataType *); \
		void (* const set)(DArray *, size_t, T *); \
	}\


typedef struct _d_array DArray;
struct _d_array {
	/* data */
	const size_t element_size;
	size_t capacity;
	size_t length;
	void *content;		
	void (* const get)(DArray *, size_t, PDataType *);
	void (* const set)(DArray *, size_t, void *);
};

typedef _darray_type_declare(float)		DArray_FLOAT;
