UTRACE_ATTACH_TASK(9)						  utrace core API					     UTRACE_ATTACH_TASK(9)

NAME

       utrace_attach_task - attach new engine, or look up an attached engine

SYNOPSIS

       struct utrace_engine * utrace_attach_task(struct task_struct * target, int flags, const struct utrace_engine_ops * ops, void * data);

ARGUMENTS

       target
	   thread to attach to

       flags
	   flag bits combined with OR, see below

       ops
	   callback table for new engine

       data
	   engine private data pointer

DESCRIPTION

       The caller must ensure that the target thread does not get freed, i.e. hold a ref or be its parent. It is always safe to call this on
       current, or on the child pointer in a report_clone callback. For most other cases, it's easier to use utrace_attach_pid instead.

UTRACE_ATTACH_CREATE
       Create a new engine. If UTRACE_ATTACH_CREATE is not specified, you only look up an existing engine already attached to the thread.

UTRACE_ATTACH_EXCLUSIVE
       Attempting to attach a second (matching) engine fails with -EEXIST.

UTRACE_ATTACH_MATCH_OPS
       Only consider engines matching ops.

UTRACE_ATTACH_MATCH_DATA
       Only consider engines matching data.

       Calls with neither UTRACE_ATTACH_MATCH_OPS nor UTRACE_ATTACH_MATCH_DATA match the first among any engines attached to target. That means
       that UTRACE_ATTACH_EXCLUSIVE in such a call fails with -EEXIST if there are any engines on target at all.

NAME

       plasmaengineexplorer - Provides direct access to plasma data engines

SYNOPSIS

       plasmaengineexplorer [--height pixels] [--width pixels] [-x pixels] [-y pixels] [--engine name] [--source name] [--interval ms]

       plasmaengineexplorer [KDE Generic Options] [Qt Generic Options]

DESCRIPTION

       plasmaengineexplorer is a graphical tool allowing developers to test Plasma data engines without writing a Plasma applet.

       If no options are given, it will start without any data engine selected. The required data engine can be selected from a drop-down list.

       Only installed data engines will be found. kbuildsycoca4 may need to be run for newly-installed data engines to be found.

OPTIONS

       --height pixels
	      Sets the height of the window, in pixels.

       --width pixels
	      Sets the width of the window, in pixels.

       -x pixels
	      Sets the x (horizontal) co-ordinate of the top left corner of the window, in pixels.

       -y pixels
	      Sets the y (vertical) co-ordinate of the top left corner of the window, in pixels.

       --engine name
	      Start  plasmaengineexplorer  with  the  given  data  engine  selected.  name  is	the  internal name of the data engine given by the
	      X-KDE-PluginInfo-Name key of the desktop file.

       --source name
	      Only valid in conjunction with --engine. Requests a specific source from the data engine when plasmaengineexplorer is started.

       --interval time
	      Sets the default update interval for requested sources to time milliseconds. If not set, the source will update on demand (for  some
	      sources, this will be when new data is available).

	      If --source is specified, this is the update interval that will be used when requesting that source.

SEE ALSO

       More detailed user documentation is available from help:/plasma (either enter this URL into Konqueror, or run khelpcenter help:/plasma).

EXAMPLES

       Load the time data engine, showing the local time and updating every second:

	      plasmaengineexplorer --engine time --source Local --interval 1000
