### H.1 Process list

When requesting the process list, the annex field in the ‘`qXfer`’ request should be ‘`processes`’. The returned data is an XML document. The formal syntax of this document is defined in `gdb/features/osdata.dtd`.

An example document is:

         <?xml version="1.0"?>
         <!DOCTYPE target SYSTEM "osdata.dtd">
         <osdata type="processes">
           <item>
             <column name="pid">1</column>
             <column name="user">root</column>
             <column name="command">/sbin/init</column>
             <column name="cores">1,2,3</column>
           </item>
         </osdata>

Each item should include a column whose name is ‘`pid`’. The value of that column should identify the process on the target. The ‘`user`’ and ‘`command`’ columns are optional, and will be displayed by gdb. The ‘`cores`’ column, if present, should contain a comma-separated list of cores that this process is running on. Target may provide additional columns, which gdb currently ignores.
