64 * as used by DosStartSession and WinStartApp (with
65 * lots of zero-terminated strings one after another

67 * input and splits it into an array of separate

75 * one newly allocated string in the array. Use

709 *@@ appStartApp:
710 * wrapper around WinStartApp which fixes the

714 * This fixes the executable info to support:
715 *
716 * -- starting "*" executables (command prompts
717 * for OS/2, DOS, Win-OS/2);
718 *
719 * -- starting ".CMD" and ".BAT" files as
720 * PROGDETAILS.pszExecutable.
721 *
722 * Unless it is "*", PROGDETAILS.pszExecutable must
723 * be a proper file name. The full path may be omitted
724 * if it is on the PATH, but the extension (.EXE etc.)
725 * must be given. You can use doshFindExecutable to
726 * find executables if you don't know the extension.
727 *
728 * This also handles and merges special and default
729 * environments for the app to be started. The
730 * following should be respected:
731 *
732 * -- As with WinStartApp, if PROGDETAILS.pszEnvironment
733 * is NULL, the new app inherits a default environment
734 * from the shell.
735 *
736 + -- However, if you specify an environment, you _must_
737 * specify a complemete environment. This function
738 * will not merge environments. Use
739 * appSetEnvironmentVar to change environment
740 * variables in a complete environment set.
741 *
742 * -- If PROGDETAILS specifies a Win-OS/2 session
743 * and PROGDETAILS.pszEnvironment is empty,
744 * this uses the default Win-OS/2 environment.
745 * See appQueryDefaultWin31Environment.
746 *
747 * Even though this isn't clearly said in PMREF,
748 * PROGDETAILS.swpInitial is important:
749 *
750 * -- To start a session minimized, set SWP_MINIMIZE.
751 *
752 * -- To start a VIO session auto-close disabled, set
753 * the half-documented SWP_NOAUTOCLOSE flag (0x8000)
754 * This flag is now in the newer toolkit headers.
755 *
756 * Since this calls WinStartApp in turn, this
757 * requires a message queue on the calling thread.
