Parameters
len
Number of elements to allocate.
Description
This function allocates memory block aligned to 64-byte boundary for elements of different data types.
Not aligned memory allocation could cause not reproducible performance and precision results.

Example

The following example shows how to use the
ippsMalloc_8u
function:
void func_malloc(void) { Ipp8u* pBuf = ippsMalloc_8u(8*sizeof(Ipp8u)); if(NULL == pBuf) // not enough memory ippsFree(pBuf); }
Return Values
The return value of
ippsMalloc
is a pointer to an aligned memory block. If no memory is available in the system, then the
NULL
value is returned. To free this block, use the
ippsFree
function.
