Feature #17832

Updated by dsisnero (Dominic Sisneros) about 3 years ago

IO#write() - arguments that are not a string will be converted to string using to_s 
 want IO#write to be able to write memoryview objects without conversion to string  

 ``` ruby 
 require 'fiddle' 
 include Fiddle 
 ptr = Fiddle::Pointer['this is a string'] 
 mv = MemoryView.new ptr 
 mv.byte_size    #17802  
 mv[0]    # 116 
 'this is a string'.bytes[0] = 116 
 File.open('test.txt', 'wb'){ f.write mv} 
 contents = File.open('test.txt', 'r'){ |f| f.read}    # contents is    "#<Fiddle::MemoryView:0x000001a75ae76258>" not 'this is a string' 

 buffer = ByteBuffer.new('this is a string') 
 File.open('test.txt', 'w'){|f| f.write Fiddle::MemoryView.new(buffer)} 
 ``` 

 allow IO#write to write memoryview objects without converting to string or add a new method on IO to write memoryview objects without converting to string
