Detailed Description

Function Documentation

mirkl_mem_array_alloc()

mirkl_error_t * mirkl_mem_array_alloc	(	mirkl_arr_t **	arr,
		mirkl_size_t	elsize,
		unsigned int	dim_first,
			...
	)

Allocates multi-dimensional array structure.

Last argument must by zero. Example of allocating 4-dimensional integer array equvivalent to int a[10][10][10][10].

error = mirkl_mem_array_alloc(&arr, sizeof(int), 10, 10, 10, 10, 0);
if(error) {
  mirkl_error_clear(mirkl_error_handle(error, mirkl_error_stdhandler, NULL));
  exit(1);
}

mirkl_mem_array_allset()

mirkl_error_t * mirkl_mem_array_allset	(	mirkl_arr_t *	arr,
		int	val,
		mirkl_size_t	elsize
	)

Set all elements of an array to one value.

// Zero all elements
error = mirkl_mem_array_allset(arr, 0, sizeof(double));
if(error) {
  mirkl_error_clear(mirkl_error_handle(error, mirkl_error_stdhandler, NULL));
  exit(1);
}

mirkl_mem_array_copyfromel()

mirkl_error_t * mirkl_mem_array_copyfromel	(	mirkl_arr_t *	arr,
		void *	eldata,
		mirkl_size_t	elsize,
		unsigned int	ndim,
		unsigned int *	npos
	)

Get value of an element of array.

Parameters are the same as in mirkl_mem_array_copytoel()

mirkl_mem_array_copytoel()

mirkl_error_t * mirkl_mem_array_copytoel	(	mirkl_arr_t *	arr,
		const void *	eldata,
		mirkl_size_t	elsize,
		unsigned int	ndim,
		unsigned int *	npos
	)

Set value of an element of array.

Copies external data to the memory of an element.

Parameters

[in]	arr	Array structure.
[in]	eldata	Data to be copied.
[in]	elsize	Size of data.
[in]	ndim	Number of dimensions in array.
[in]	npos	An array of indices indicating position of the element.

mirkl_mem_array_free()

void mirkl_mem_array_free

(

mirkl_arr_t *

arr

)

Destroying array structure.

Parameters

[in]

arr

Pointer to the array structure to be destroyed. Not valid after calling this function.
