Class Method Summary

• .raptor_free_string ⇒ Object
• .raptor_new_string(str) ⇒ FFI::Pointer

  Allocates memory for the string str inside libraptor, copying the string into the newly-allocated buffer.

Class Method Details

.raptor_free_string ⇒ Object

# File 'lib/rdf/raptor/ffi/v1.rb', line 130

alias_method :raptor_free_string, :raptor_free_memory

.raptor_new_string(str) ⇒ FFI::Pointer

Allocates memory for the string str inside libraptor, copying the string into the newly-allocated buffer.

The buffer should later be deallocated using raptor_free_string.

Returns:

• (FFI::Pointer)

# File 'lib/rdf/raptor/ffi/v1.rb', line 123

def raptor_new_string(str)
  ptr = V1.raptor_alloc_memory(str.bytesize + 1)
  ptr.put_string(0, str)
  ptr
