network programming - SCTP protocol support in android -


how can use sctp protocol in android?

i'm aware that android systems don't support sctp default, it's may possible enable inserting sctp kernel module, or rebuilding kernel sctp enabled in modules configuration.

i need insight on issue. possible? how make android support protocol? how build kernel module , insert correctly? if succeed in making system support it, how can use protocol? java api on android support sctp?

going module right way. answer questions:

  • sctp provided kernel module in linux source tree - "config_ip_sctp=m" enable module. , can change "y" hard link, though unfeasible, since you'd have rebuild entire kernel that.

  • the module have still built per kernel version. per vendor, you'd need kernel sources (doable), , compile module against it.

to use: in user mode - create socket calling s = socket (af_inet[6], sock_stream, ipproto_sctp); point, socket apis work same, few exceptions (namely setsockopt, particular protocol type).

from java - in fact support protocol in latest incarnations (jdk7 of milestone 3), java supports doesn't mean dalvik (the "java vm" of android) does. though android have sctp support "in ready", it's not yet in dalvik (at least not in 4.2). create java class, though, in package, wrap native library sctp calls. it's bit trickier in android because of net permissions, still manageable (from experience).

Why does Ruby on Rails generate add a blank line to the end of a file? -

running rails generate controller foo home results in: class foocontroller < application controller def home end end (there's nothing on line in actual file, blank line) is there purpose blank line? it's common use newline indicate end of line, last line. many editors (like vi, use) add in newline silently. consensus text files (especially in unix world) should end in newline, , there have been problems historically if wasn't present. why should text files end newline? the tool used count lines in file "wc" counts newlines in file, without trailing newline show 3 instead of 4. it improves readability of templates used in generator. consider: https://github.com/rails/rails/blob/master/railties/lib/rails/generators/rails/controller/templates/controller.rb to remove trailing newline, template have last line of: end<% end -%> instead of: end <% end -%> that seems less readable me. the discussion below refers
