Third Parties Software L-Z
This chapter lists selector codes of which the meaning is known or documented and are installed by Third Parties software, and the first character of the selector code is in the L-Z range.
Lnch (Network Time cp [2.0] by Pete Resnick)
(First Launch Gestalt INIT code resource, by Pete Resnick)
gestaltFirstLaunchAttr
Returns info on whether the _Launch trap has been called by the
System.
enum {
#define gestaltFirstLaunchAttr 'Lnch' /* _Launch information */
gestaltFirstLaunchDone = 0}; /* _Launch called, INIT time over */
NOTE:
Bit 0 of the response, gestaltFirstLaunchDone, indicates whether the
_Launch trap has been called since startup of the machine. All other
bits are reserved and currently 0. Even if not installed at INIT time,
Network Time will install the Gestalt selector if it is not already
there when the control panel is opened and automatically set
bit 0 to 1.
68000 assembler source code is available for the INIT that installs
the selector, and INIT resource -4048 from Network Time may be
stolen (and renumbered as desired) and used in any INIT file as
desired. (Pete Resnick)
