/*
* GetProcessPID()
*
* Summary:
* Get the UNIX process ID corresponding to a process.
*
* Discussion:
* Given a Process serial number, this call will get the UNIX
* process ID for that process. Note that this call does not make
* sense for Classic apps, since they all share a single UNIX
* process ID.
*
* Parameters:
*
* psn:
* Serial number of the target process
*
* pid:
* UNIX process ID of the process
*
* Availability:
* Mac OS X: in version 10.0 and later in
ApplicationServices.framework
* CarbonLib: not available in CarbonLib 1.x, is available on
Mac OS X version 10.0 and later
* Non-Carbon CFM: not available

Hi
I would to know the Unix ID number of a process. I have found the code
to get the processes list. Is there a method to get, from here, the
unix pid of the process?
- (NSArray *)Process {
NSMutableArray *resultsArray=[NSMutableArray array];
OSErr resultCode=noErr;
ProcessSerialNumber serialNumber;
ProcessInfoRec procInfo;
FSSpec appFSSpec;
Str255 procName;
serialNumber.highLongOfPSN = kNoProcess;
serialNumber.lowLongOfPSN = kNoProcess;
procInfo.processInfoLength =sizeof(ProcessInfoRec);
procInfo.processName=procName;
procInfo.processAppSpec = &appFSSpec;
procInfo.processAppSpec = &appFSSpec;
while (procNotFound != (resultCode =
GetNextProcess(&serialNumber))) {
if (noErr ==(resultCode =
GetProcessInformation(&serialNumber,&procInfo))) {
if (procName[1] == nil) procName[1] = '0';
[resultsArray
addObject:(NSString*)CFStringCreateWithPascalString(NULL,procInfo.proce
ssName,kCFStringEncodingMacRoman)];
}
}
return resultsArray;
}
Thank you to all
Good work
