=head1 NAME
-OS2::Process - exports constants for system() call on OS2.
+OS2::Process - exports constants for system() call, and process control on OS2.
=head1 SYNOPSIS
use OS2::Process;
- $pid = system(P_PM+P_BACKGROUND, "epm.exe");
+ $pid = system(P_PM | P_BACKGROUND, "epm.exe");
=head1 DESCRIPTION
+=head2 Optional argument to system()
+
the builtin function system() under OS/2 allows an optional first
argument which denotes the mode of the process. Note that this argument is
recognized only if it is strictly numerical.
=head2 Access to process properties
-Additionaly, subroutines my_type(), process_entry() and
-C<file_type(file)>, get_title() and C<set_title(newtitle)> are implemented.
-my_type() returns the type of the current process (one of
-"FS", "DOS", "VIO", "PM", "DETACH" and "UNKNOWN"), or C<undef> on error.
+On OS/2 processes have the usual I<parent/child> semantic;
+additionally, there is a hierarchy of sessions with their own
+I<parent/child> tree. A session is either a FS session, or a windowed
+pseudo-session created by PM. A session is a "unit of user
+interaction", a change to in/out settings in one of them does not
+affect other sessions.
=over
-=item C<file_type(file)>
+=item my_type()
+
+returns the type of the current process (one of
+"FS", "DOS", "VIO", "PM", "DETACH" and "UNKNOWN"), or C<undef> on error.

-Set to 1 for 32-bit executable files.
+Set to 1 for 32-bit executable files.

to suppress).
+=item C<@list = process_codepages()>
+
+the first element is the currently active codepage, up to 2 additional
+entries specify the system's "prepared codepages": the codepages the
+user can switch to. The active codepage of a process is one of the
+prepared codepages of the system (if present).
+
+=item C<process_codepage_set($cp)>
+
+sets the currently active codepage. [Affects printer output, in/out
+codepages of sessions started by this process, and the default
+codepage for drawing in PM; is inherited by kids. Does not affect the
+out- and in-codepages of the session.]
+
+=item ppid()
+
+returns the PID of the parent process.
+
+=item C<ppidOf($pid = $$)>
+
+returns the PID of the parent process of $pid. -1 on error.
+
+=item C<sidOf($pid = $$)>
+
+returns the session id of the process id $pid. -1 on error.

+
+=head2 Control of VIO sessions
+
+VIO applications are applications running in a text-mode session.
+

+
+=item out_codepage()
+
+gets code page used for screen output (glyphs). -1 means that a user font
+was loaded.
+
+=item C<out_codepage_set($cp)>
+
+sets code page used for screen output (glyphs). -1 switches to a preloaded
+user font. -2 switches off the preloaded user font.
+
+=item in_codepage()
+
+gets code page used for keyboard input. 0 means that a hardware codepage
+is used.
+
+=item C<in_codepage_set($cp)>
+
+sets code page used for keyboard input.
+
+=item C<($w, $h) = scrsize()>
+
+width and height of the given console window in character cells.
+
+=item C<scrsize_set([$w, ] $h)>
+
+set height (and optionally width) of the given console window in
+character cells. Use 0 size to keep the old size.
+
+=item C<($s, $e, $w, $a) = cursor()>
+
+gets start/end lines of the blinking cursor in the charcell, its width
+(1 on text modes) and attribute (-1 for hidden, in text modes other
+values mean visible, in graphic modes color).
+
+=item C<cursor_set($s, $e, [$w [, $a]])>
+
+sets start/end lines of the blinking cursor in the charcell. Negative
+values mean percents of the character cell height.
+
+=item screen()
+
+gets a buffer with characters and attributes of the screen.
+
+=item C<screen_set($buffer)>
+
+restores the screen given the result of screen().

+
+=item process_hentries()

+for a funny - and wrong - explanation ;-). In such cases a
+direct-manipulation of low-level entries is used. Keep in mind that
+some versions of OS/2 leak memory with such a manipulation.
+
+=item C<SwitchToProgram($sw_entry)>
+
+switch to session given by a switch list handle.
+
+Use of this function causes another window (and its related windows)
+of a PM session to appear on the front of the screen, or a switch to
+another session in the case of a non-PM program. In either case,
+the keyboard (and mouse for the non-PM case) input is directed to
+the new program.
+
+=back
+
+=head2 Control of the PM windows
+
+Some of these API's require sending a message to the specified window.
+In such a case the process needs to be a PM process, or to be morphed
+to a PM process via OS2::MorphPM().
+
+For a temporary morphing to PM use L<OS2::localMorphPM class>.
+
+Keep in mind that PM windows are engaged in 2 "orthogonal" window
+trees, as well as in the z-order list.
+
+One tree is given by the I<parent/child> relationship. This
+relationship affects drawing (child is drawn relative to its parent
+(lower-left corner), and the drawing is clipped by the parent's
+boundary; parent may request that I<it's> drawing is clipped to be
+confined to the outsize of the childs and/or siblings' windows);
+hiding; minimizing/restoring; and destroying windows.
+
+Another tree (not necessarily connected?) is given by I<ownership>
+relationship. Ownership relationship assumes cooperation of the
+engaged windows via passing messages on "important events"; e.g.,
+scrollbars send information messages when the "bar" is moved, menus
+send messages when an item is selected; frames
+move/hide/unhide/minimize/restore/change-z-order-of owned frames when
+the owner is moved/etc., and destroy the owned frames (even when these
+frames are not descendants) when the owner is destroyed; etc. [An
+important restriction on ownership is that owner should be created by
+the same thread as the owned thread, so they engage in the same
+message queue.]
+
+Windows may be in many different state: Focused, Activated (=Windows
+in the I<parent/child> tree between the root and the window with
+focus; usually indicate such "active state" by titlebar highlights),
+Enabled/Disabled (this influences *an ability* to receive user input
+(be focused?), and may change appearance, as for enabled/disabled
+buttons), Visible/Hidden, Minimized/Maximized/Restored, Modal, etc.
+

+
+First item in the same group.
+
+=item EDI_FIRSTTABITEM
+
+First item in dialog with style WS_TABSTOP. hwnd is ignored.
+
+=item EDI_LASTGROUPITEM
+
+Last item in the same group.

+=head1 OS2::localMorphPM class
+
+This class morphs the process to PM for the duration of the given context.
+
+ {
+ my $h = OS2::localMorphPM->new(0);
+ # Do something
+ }
+
+The argument has the same meaning as one to OS2::MorphPM(). Calls can
+nest with internal ones being NOPs.
+
+=head1 TODO
+
+Constants (currently one needs to get them looking in a header file):
+
+ HWND_*
+ WM_* /* Separate module? */
+ SC_*
+ SWP_*
+ WC_*
+ PROG_*
+ QW_*
+ EDI_*
+ WS_*
+
+Show/Hide, Enable/Disable (WinShowWindow(), WinIsWindowVisible(),
+WinEnableWindow(), WinIsWindowEnabled()).
+
+Maximize/minimize/restore via WindowPos_set(), check via checking
+WS_MAXIMIZED/WS_MINIMIZED flags (how to get them?).
+
+=head1 $^E
+
+the majority of the APIs of this module set $^E on failure (no matter
+whether they die() on failure or not). By the semantic of PM API
+which returns something other than a boolean, it is impossible to
+distinguish failure from a "normal" 0-return. In such cases C<$^E ==
+0> indicates an absence of error.
+
+=head1 BUGS
+
+whether a given API dies or returns FALSE/empty-list on error may be
+confusing. This may change in the future.
