Function randomx_create_vm

pub unsafe extern "C" fn randomx_create_vm(
    flags: randomx_flags,
    cache: *mut randomx_cache,
    dataset: *mut randomx_dataset,
) -> *mut randomx_vm

Creates and initializes a RandomX virtual machine.

     @param flags is any combination of these 5 flags (each flag can be set or not set):
             RANDOMX_FLAG_LARGE_PAGES - allocate scratchpad memory in large pages
             RANDOMX_FLAG_HARD_AES - virtual machine will use hardware accelerated AES
             RANDOMX_FLAG_FULL_MEM - virtual machine will use the full dataset
             RANDOMX_FLAG_JIT - virtual machine will use a JIT compiler
             RANDOMX_FLAG_SECURE - when combined with RANDOMX_FLAG_JIT, the JIT pages are never
                                   writable and executable at the same time (W^X policy)
             The numeric values of the first 4 flags are ordered so that a higher value will provide
             faster hash calculation and a lower numeric value will provide higher portability.
             Using RANDOMX_FLAG_DEFAULT (all flags not set) works on all platforms, but is the slowest.
     @param cache is a pointer to an initialized randomx_cache structure. Can be
             NULL if RANDOMX_FLAG_FULL_MEM is set.
     @param dataset is a pointer to a randomx_dataset structure. Can be NULL
             if RANDOMX_FLAG_FULL_MEM is not set.

     @return Pointer to an initialized randomx_vm structure.
             Returns NULL if:
             (1) Scratchpad memory allocation fails.
             (2) The requested initialization flags are not supported on the current platform.
             (3) cache parameter is NULL and RANDOMX_FLAG_FULL_MEM is not set
             (4) dataset parameter is NULL and RANDOMX_FLAG_FULL_MEM is set
