```
public static java.nio.ByteBuffer malloc(int size)
```
    Allocate a new ByteBuffer from memory
    
    Parameters:
    size - The amount of memory to allocate
    
    Returns:
    The ByteBuffer with allocated memory
  - calloc
```
public static java.nio.ByteBuffer calloc(int num,
                         int size)
```
    Allocate a new ByteBuffer from memory and set all of the memory to 0
    
    Parameters:
    num - Number of elements.
    size - Length in bytes of each element.
    
    Returns:
    The ByteBuffer with allocated memory
  - palloc
```
public static java.nio.ByteBuffer palloc(long p,
                         int size)
```
    Allocate a new ByteBuffer from a pool
    
    Parameters:
    p - The pool to allocate from
    size - The amount of memory to allocate
    
    Returns:
    The ByteBuffer with allocated memory
  - pcalloc
```
public static java.nio.ByteBuffer pcalloc(long p,
                          int size)
```
    Allocate a new ByteBuffer from a pool and set all of the memory to 0
    
    Parameters:
    p - The pool to allocate from
    size - The amount of memory to allocate
    
    Returns:
    The ByteBuffer with allocated memory
  - create
```
public static java.nio.ByteBuffer create(long mem,
                         int size)
```
    Allocate a new ByteBuffer from already allocated memory.
    Allocated memory must be provided from call to the Stdlib.alloc or Stdlib.calloc methods.
    
    Parameters:
    mem - The memory to use
    size - The amount of memory to use
    
    Returns:
    The ByteBuffer with attached memory
  - free
```
public static void free(java.nio.ByteBuffer buf)
```
    Deallocates or frees a memory block used by ByteBuffer
    Warning : Call this method only on ByteBuffers that were created by calling Buffer.alloc or Buffer.calloc.
    
    Parameters:
    buf - Previously allocated ByteBuffer to be freed.
  - address
```
public static long address(java.nio.ByteBuffer buf)
```
    Returns the memory address of the ByteBuffer.
    
    Parameters:
    buf - Previously allocated ByteBuffer.
  - size
```
public static long size(java.nio.ByteBuffer buf)
```
    Returns the allocated memory size of the ByteBuffer.
    
    Parameters:
    buf - Previously allocated ByteBuffer.
