Parameters

len	Number of elements to allocate.

Description

The function ippsMalloc is declared in the ipps.h file. This function allocates memory block aligned to a 32-byte boundary for elements of different data types.

The example below shows how to use the function ippsMalloc_8u.

Using the Function ippsMalloc

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 function ippsFree.
