Method: Array#ffi_mem_pointer_int64

Defined in:
lib/hdf5.rb

#ffi_mem_pointer_int64 ⇒ Object

Allocate an integer64 chunk of memory, copy the contents of the array into it and return an FFI::MemoryPointer to the memory. The memory will be garbage collected when the pointer goes out of scope. Obviously the array should contain only integers. This method is not fast and shouldn’t be used for giant arrays.

Raises:

  • (TypeError)
