  - malloc
```
public static java.nio.ByteBuffer malloc(long size)
```
    Allocates size bytes and returns a pointer to the allocated memory. The memory is not initialized. If size is 0, then malloc() returns either NULL, or a unique pointer value that can later be successfully passed to Stdlib.free(java.nio.ByteBuffer).
    
    Parameters:
    
    size - the number of bytes to allocate
  - calloc
```
public static java.nio.ByteBuffer calloc(long nmemb,
                                         long size)
```
    Allocates memory for an array of nmemb elements of size bytes each and returns a pointer to the allocated memory. The memory is set to zero. If nmemb or size is 0, then calloc() returns either NULL, or a unique pointer value that can later be successfully passed to Stdlib.free(java.nio.ByteBuffer).
    
    Parameters:
    
    nmemb - the number of elements to allocate
    
    size - the number of bytes to allocate per element
  - realloc
```
public static java.nio.ByteBuffer realloc(java.nio.ByteBuffer ptr,
                                          long size)
```
    Changes the size of the memory block pointed to by ptr to size bytes The contents will be unchanged in the range from the start of the region up to the minimum of the old and new sizes. If the new size is larger than the old size, the added memory will not be initialized. If ptr is NULL, then the call is equivalent to malloc(size), for all values of size; if size is equal to zero, and ptr is not NULL, then the call is equivalent to free(ptr). Unless ptr is NULL, it must have been returned by an earlier call to Stdlib.malloc(long), Stdlib.calloc(long, long) or Stdlib.realloc(java.nio.ByteBuffer, long). If the area pointed to was moved, a free(ptr) is done.
    
    Parameters:
    
    ptr - the memory block to reallocate
    
    size - the new memory block size, in bytes
  - free
```
public static void free(java.nio.ByteBuffer ptr)
```
    Frees the memory space pointed to by ptr, which must have been returned by a previous call to Stdlib.malloc(long), Stdlib.calloc(long, long), or Stdlib.realloc(java.nio.ByteBuffer, long). Otherwise, or if free(ptr) has already been called before, undefined behavior occurs. If ptr is NULL, no operation is performed.
    
    Parameters:
    
    ptr - the memory space to free
  - free

                                                long size)
```
    Allocates size bytes of uninitialized storage whose alignment is specified by alignment. The size parameter must be an integral multiple of alignment. Memory allocated with aligned_alloc() must be freed with Stdlib.aligned_free(java.nio.ByteBuffer).
    
    Parameters:
    
    alignment - the alignment. Must be a power of two value.
    
    size - the number of bytes to allocate. Must be a multiple of alignment.
  - aligned_free
```
public static void aligned_free(java.nio.ByteBuffer ptr)
```
    Frees a block of memory that was allocated with Stdlib.aligned_alloc(long, long). If ptr is NULL, no operation is performed.

    ptr - the aligned block of memory to free
