--- !ruby/object:RI::MethodDescription aliases: [] block_params: comment: - !ruby/struct:SM::Flow::P body: Reads at most <em>maxlen</em> bytes from <em>ios</em> using read(2) system call after O_NONBLOCK is set for the underlying file descriptor. - !ruby/struct:SM::Flow::P body: If the optional <em>outbuf</em> argument is present, it must reference a String, which will receive the data. - !ruby/struct:SM::Flow::P body: "read_nonblock just calls read(2). It causes all errors read(2) causes: EAGAIN, EINTR, etc. The caller should care such errors." - !ruby/struct:SM::Flow::P body: read_nonblock causes EOFError on EOF. - !ruby/struct:SM::Flow::P body: If the read buffer is not empty, read_nonblock reads from the buffer like readpartial. In this case, read(2) is not called. full_name: IO#read_nonblock is_singleton: false name: read_nonblock params: | ios.read_nonblock(maxlen) => string ios.read_nonblock(maxlen, outbuf) => outbuf visibility: public
