Method Summary

All Methods Instance Methods Abstract Methods
Modifier and Type	Method	Description
`com.sun.jna.Pointer`	`invoke(com.sun.jna.Pointer ptr, SizeT old_size, SizeT new_size)`	Resize a previously allocated block `ptr` of `old_size` bytes to be `new_size` bytes.

- Method Detail
  - invoke
```
com.sun.jna.Pointer invoke(com.sun.jna.Pointer ptr,
                           SizeT old_size,
                           SizeT new_size)
```
    Resize a previously allocated block ptr of old_size bytes to be new_size bytes. The block may be moved if necessary or if desired, and in that case the smaller of old_size and new_size bytes must be copied to the new location. The return value is a pointer to the resized block, that being the new location if moved or just ptr if not.
    ptr is never NULL, it’s always a previously allocated block. new_size may be bigger or smaller than old_size.
