Concurrent ML (CML) is a concurrent extension of the Standard ML programming language. ==Sample Code== Here is sample code to print "hello, world" to the console. It spawns a thread which creates a channel for strings. This thread then spawns another thread which prints the first string that is received on the channel. The former thread then sends the "hello, world\n" string on the channel. It uses SML/NJ and CML (note that the heap name will be different on non linux-x86 platforms; you may need to change the line with "cml_test.x86-linux" to something different): cml_test.cm: Library structure Hello is $cml/basis.cm $cml/cml.cm cml_test.sml cml_test.sml: structure Hello = struct open CML fun hello () = let val c : string chan = channel () in spawn (fn () => TextIO.print (recv c)); send (c, "hello, world\n"); exit () end fun main (name, argv) = RunCML.doit (fn () => ignore (spawn hello), NONE) end Running: $ ml-build cml_test.cm Hello.main Standard ML of New Jersey v110.60 (Mon Nov 27 14:19:21 2006 ) (cml_test.cm ) ($cml/basis.cm is stable ) ($cml/cml.cm is stable ) ((cml_test.cm):cml_test.sml ) (directory .cm/SKEL ) ($cml/cml-internal.cm is stable ) ($cml/core-cml.cm is stable ) ($SMLNJ-BASIS/basis.cm is stable ) ((cml_test.cm):cml_test.sml ) (directory .cm/GUID ) (directory .cm/x86-unix ) (2170, data: 42, env: 2561 bytes ) (18518-export.cm ) ((18518-export.cm):cml_test.cm ) ((18518-export.cm):18518-export.sml ) ((18518-export.cm):18518-export.sml ) (309, data: 37, env: 42 bytes ) $ heap2exec cml_test.x86-linux cml_test $ ./cml_test hello, world 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「Concurrent ML」の詳細全文を読む スポンサード リンク
