Detailed Description

Functions for reading and writing array elements.

Function Documentation

da_data()

DA_DEF void * da_data

(

da_array

arr

)

Gets direct pointer to the underlying data array.

Parameters

arr	Array to access (must not be NULL)

Returns

Pointer to raw data array (like stb_ds.h style)

Note

Enables direct indexing: ((int*)da_data(arr))[i]

Pointer is valid until array is modified or released

No bounds checking - use with care

int* data = (int*)da_data(arr);
data[0] = 42;  // Direct array-style access
data[1] = 99;

da_get()

DA_DEF void * da_get	(	da_array	arr,
		int	index
	)

Gets a pointer to an element at the specified index.

Parameters

arr	Array to access (must not be NULL)
index	Element index (must be >= 0 and < length)

Returns

Pointer to element at index

Note

Asserts on out-of-bounds access

Returned pointer is valid until array is modified or released

int* ptr = (int*)da_get(arr, 0);
*ptr = 42;  // Direct modification

da_set()

DA_DEF void da_set	(	da_array	arr,
		int	index,
		const void *	element
	)

Sets the value of an element at the specified index.

Parameters

arr	Array to modify (must not be NULL)
index	Element index (must be >= 0 and < length)
element	Pointer to element data to copy (must not be NULL)

Note

Asserts on out-of-bounds access or NULL parameters

Copies element_size bytes from element pointer

int value = 42;
da_set(arr, 0, &value);
