(Note: In UTF-8 all standard ansi characters, 0-127 are the same as a standard ansi encoding. Also, no ansi character appears in any multi-byte characters. So, you can use standard C functions like <function>strlen</function>, and <function>strcpy</function> just fine with UTF-8 encoded strings. For example: <returnvalue>OK</returnvalue> encoded in UTF-8 is simply <returnvalue>OK</returnvalue>. For more information on UTF=8: http://www.cl.cam.ac.uk/~mgk25/unicode.html#utf-8) </para> </section> <section> <title>Responses</title> <para> A command returns <returnvalue>OK</returnvalue> on completion or <returnvalue>ACK some error</returnvalue> on failure. These denote the end of command execution. </para> </section> <section> <title>Command lists</title> <para> To facilitate faster adding of files etc. you can pass a list of commands all at once using a command list.

The return value is whatever the return for a list of commands is. On success for all commands, <returnvalue>OK</returnvalue> is returned. If a command fails, no more commands are executed and the appropriate <returnvalue>ACK</returnvalue> error is returned. If <command>command_list_ok_begin</command> is used, <returnvalue>list_OK</returnvalue> is returned for each successful command executed in the command list. </para> </section> <section> <title>Ranges</title> <para> Some commands (e.g. <link linkend="command_delete"><command>delete</command></link>) allow specifying a range in the form <parameter>START:END</parameter> (the <varname>END</varname> item is not included in the range, similar to ranges in the Python programming language). If <varname>END</varname> is omitted, then the maximum possible value is assumed. </para> </section> </chapter> <chapter> <title>Command reference</title> <note> <para> For manipulating playlists and playing, there are two sets of commands. One set uses the song id of a song in the playlist, while another set uses the playlist position of the song. The commands using song ids should be used instead of the commands that manipulate and control playback based on playlist position. Using song ids is a safer method when multiple clients are interacting with MPD. </para> </note> <section> <title>Querying MPD's status</title> <variablelist> <varlistentry id="command_clearerror"> <term> <cmdsynopsis> <command>clearerror</command> </cmdsynopsis> </term> <listitem> <para> Clears the current error message in status (this is also accomplished by any command that starts playback). </para> </listitem> </varlistentry> <varlistentry id="command_currentsong"> <term> <cmdsynopsis> <command>currentsong</command> </cmdsynopsis> </term> <listitem> <para> Displays the song info of the current song (same song that is identified in status). </para> </listitem> </varlistentry> <varlistentry id="command_idle"> <term> <cmdsynopsis> <command>idle</command> <arg choice="opt" rep="repeat"><replaceable>SUBSYSTEMS</replaceable></arg> </cmdsynopsis> </term> <listitem> <para> <footnote id="since_0_14"><simpara>Introduced with MPD 0.14</simpara></footnote> Waits until there is a noteworthy change in one or more of MPD's subsystems.
