Number of elements to allocate. |
Description
This function allocates memory block aligned to 64-byte boundary for elements of different data types.
Example
The following example shows how to use theippsMalloc_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.
