Reads at most maxlen bytes from the gziped stream but it blocks only if gzipreader has no data immediately available. If the optional outbuf argument is present, it must reference a String, which will receive the data. It raises EOFError on end of file.

Returns true if the effective user id of the process is the same as the owner of stat.

File.stat("testfile").owned?      #=> true
File.stat("/etc/passwd").owned?   #=> false

Returns true if the effective group id of the process is the same as the group id of stat. On Windows, returns false.

File.stat("testfile").grpowned?      #=> true
File.stat("/etc/passwd").grpowned?   #=> false

Returns true if the file is a character device, false if it isn’t or if the operating system doesn’t support this feature.

File.stat("/dev/tty").chardev?   #=> true

Transfers ownership of the underlying memory to a new buffer, causing the current buffer to become uninitialized.

buffer = IO::Buffer.new('test')
other = buffer.transfer
other
# =>
# #<IO::Buffer 0x00007f136a15f7b0+4 SLICE>
# 0x00000000  74 65 73 74                                     test
buffer
# =>
# #<IO::Buffer 0x0000000000000000+0 NULL>
buffer.null?
# => true

If the buffer is shared, meaning it references memory that can be shared with other processes (and thus might change without being modified locally).

# Create a test file:
File.write('test.txt', 'test')

# Create a shared mapping from the given file, the file must be opened in
# read-write mode unless we also specify IO::Buffer::READONLY:
buffer = IO::Buffer.map(File.open('test.txt', 'r+'), nil, 0)
# => #<IO::Buffer 0x00007f1bffd5e000+4 EXTERNAL MAPPED SHARED>

# Write to the buffer, which will modify the mapped file:
buffer.set_string('b', 0)
# => 1

# The file itself is modified:
File.read('test.txt')
# => "best"

Fill buffer with value, starting with offset and going for length bytes.

buffer = IO::Buffer.for('test')
# =>
#   <IO::Buffer 0x00007fca40087c38+4 SLICE>
#   0x00000000  74 65 73 74         test

buffer.clear
# =>
#   <IO::Buffer 0x00007fca40087c38+4 SLICE>
#   0x00000000  00 00 00 00         ....

buf.clear(1) # fill with 1
# =>
#   <IO::Buffer 0x00007fca40087c38+4 SLICE>
#   0x00000000  01 01 01 01         ....

buffer.clear(2, 1, 2) # fill with 2, starting from offset 1, for 2 bytes
# =>
#   <IO::Buffer 0x00007fca40087c38+4 SLICE>
#   0x00000000  01 02 02 01         ....

buffer.clear(2, 1) # fill with 2, starting from offset 1
# =>
#   <IO::Buffer 0x00007fca40087c38+4 SLICE>
#   0x00000000  01 02 02 02         ....

Parse a raw cookie string into a hash of cookie-name=>Cookie pairs.

cookies = CGI::Cookie.parse("raw_cookie_string")
  # { "name1" => cookie1, "name2" => cookie2, ... }

A set of tasks to prepare the file in order to parse it
