module SleepyPenguin # call-seq: # SleepyPenguin.copy_file_range(src, dst, len[, keywords]) => # Integer # # Performs and in-kernel copy of +len+ bytes from +src+ to +dst+, # where +src+ and +dst+ are regular files on the same filesystem. # Returns the number of bytes copied, which may be less than # requested. # # +flags+ is currently unused, but may be specified in the future. # # Keywords: # # :off_in and :off_out if non-nil may be used to specify an Integer # offset for each respective descriptor. If specified, the file # offsets of each file description will not be moved, providing # pread(2)/pwrite(2)-like semantics. # # See copy_file_range(2) manpage for full documentation: # http://man7.org/linux/man-pages/man2/copy_file_range.2.html # # This method only works in Linux 4.5+ with sleepy_penguin 3.5.0+, # and may require up-to-date kernel headers for non-x86/x86-64 systems. def self.copy_file_range(io_in, io_out, len, flags = 0, off_in: nil, off_out: nil) __cfr(io_in, off_in, io_out, off_out, len, flags) end end
