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.
