WebCRYPTO_secure_malloc_init () creates the secure heap, with the specified size in bytes. The minsize parameter is the minimum size to allocate from the heap. Both size and minsize must be a power of two. CRYPTO_secure_malloc_initialized () indicates whether or not the secure heap as been initialized and is available. WebIn dlmalloc, the smallest allowed allocation is 32 bytes on a 64-bit system. Going back to the malloc (1) question, 8 bytes of overhead are added to our need for a single byte, and the …
