Method Detail

• malloc

  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:

• 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.
