--- !ruby/object:RI::MethodDescription aliases: [] block_params: comment: - !ruby/struct:SM::Flow::P body: Pushes back one character (passed as a parameter) onto <em>ios</em>, such that a subsequent buffered read will return it. Only one character may be pushed back before a subsequent read operation (that is, you will be able to read only the last of several characters that have been pushed back). Has no effect with unbuffered reads (such as <tt>IO#sysread</tt>). - !ruby/struct:SM::Flow::VERB body: " f = File.new(&quot;testfile&quot;) #=&gt; #&lt;File:testfile&gt;\n c = f.getc #=&gt; 84\n f.ungetc(c) #=&gt; nil\n f.getc #=&gt; 84\n" full_name: IO#ungetc is_singleton: false name: ungetc params: | ios.ungetc(integer) => nil visibility: public
