DESCRIPTION
Access to Inside Macintosh is essential for proper use of these functions. Explanations of terms,
processes and procedures are provided there. Any attempt to use these functions without guidance can
cause severe errors in your machine, including corruption of data. You have been warned.

LaunchParam
This Perl hash maps onto the fields of a Launch Parameter Block.
The fields are:
launchFileFlags
launchControlFlags
launchAppSpec
launchAvailableSize
launchProcessSN
launchPreferredSize
launchMinimumSize
new LaunchParam [ARGUMENTS]
Returns LaunchParam.
$launch =
new LaunchParam(launchAppSpec =E<gt> "hd:apps:myapp", launchMinimumSize => 32000);
DESTROY LPB
ProcessInfo
This Perl hash allows access to the "ProcessInfo" structure.
The field names are:
processName
processNumber
processType
processSignature
processSize
processMode
processLocation
processLauncher
processLaunchDate
processActiveTime
processAppSpec
DESTROY PI
Functions
LaunchApplication LAUNCHPARAMS
The LaunchApplication function launches the application from the specified file and returns the
process serial number if the application is successfully launched. Returns undef on failure.
LaunchDeskAccessory PFILESPEC, PDANAME
Mac OS only.
The LaunchDeskAccessory function searches the resource fork of the file specified by the
pFileSpec parameter for the desk accessory with the 'DRVR' resource name specified in the pDAName
parameter. If the 'DRVR' resource name is found, LaunchDeskAccessory launches the corresponding
desk accessory. If the desk accessory is already open, it is brought to the front. Returns zero
on failure.
GetCurrentProcess
The GetCurrentProcess function returns the process serial number of the process that is currently
running, that is, the one currently accessing the CPU. Return "undef" if an error was detected.
GetFrontProcess
The GetFrontProcess function returns the process serial number of the process running in the
foreground. Return "undef" if an error was detected.
GetNextProcess PSN
Get information about the next process, if any, in the Process ManagerO~s internal list of open
processes. Return "undef" if an error was detected.
GetProcessInformation PSN
The GetProcessInformation function returns, in a process information record, information about
the specified process. The information returned in the info parameter includes the applicationO~s
name as it appears in the Application menu, the type and signature of the application, the
address of the application partition, the number of bytes in the application partition, the
number of free bytes in the application heap, the application that launched the application, the
time at which the application was launched, and the location of the application file. Return
"undef" if an error was detected.
SetFrontProcess PSN
The SetFrontProcess function schedules the specified process to move to the foreground. The
specified process moves to the foreground after the current foreground process makes a subsequent
call to WaitNextEvent or EventAvail. Returns zero on failure.
WakeUpProcess PSN
The WakeUpProcess function makes a process suspended by WaitNextEvent() eligible to receive CPU
time. A process is suspended when the value of the sleep parameter in the WaitNextEvent()
function is not 0 and no events for that process are pending in the event queue. This process
remains suspended until the time specified in the sleep parameter expires or an event becomes
available for that process. You can use WakeUpProcess to make the process eligible for execution
before the time specified in the sleep parameter expires. Returns zero on failure.
SameProcess PSN1, PSN2
The SameProcess function compares two process serial numbers and determines whether they refer to
the same process. Return "undef" if an error was detected.
ExitToShell
This function is not implemented: ExitToShell() unsupported. Use exit.
GetProcessPID(PSN)
Mac OS X only.
Get the UNIX process ID corresponding to a process serial number.
GetProcessForPID(PID)
Mac OS X only.
Get the process serial number corresponding to a UNIX process ID.
LSFindApplicationForInfo(creator, bundleID=NULL, name=NULL)
Mac OS X only.
Return the path to the application matching one or more of creator, bundleID, and name. Pass
undef or empty string for unused parameters.
$path = LSFindApplicationForInfo("R*ch");
$path = LSFindApplicationForInfo(undef, "com.barebones.bbedit");
$path = LSFindApplicationForInfo(undef, undef, "BBEdit.app");
$path = LSFindApplicationForInfo("R*ch", "com.barebones.bbedit", "BBEdit.app");
