Parent process name and process that launched me name ?

How to get parent process name and "process that launched me"' name ?

int getprocessname( pid_t inPID, char *outName, size_t inMaxLen)
struct kinfo_proc info;
size_t length = sizeof(struct kinfo_proc);
int mib[4] = { CTL_KERN, KERN_PROC, KERN_PROC_PID, inPID };

if (sysctl(mib, 4, &info, &length, NULL, 0) < 0)
return -1 ;
strncpy(outName, info.kp_proc.p_comm, inMaxLen) ;

return 0 ;
To get the "process that launched me" name:
NSString *parentProcessName(void)
// Get our PSN
OSStatus err;
ProcessSerialNumber currPSN;
err = GetCurrentProcess (&currPSN);
if (!err) {
// Get information about our process
NSDictionary* currDict = (NSDictionary*)ProcessInformationCopyDictionary (&currPSN, kProcessDictionaryIncludeAllInformationMask);

// Get the PSN of the app that *launched* us. Its not really the parent app, in the unix sense.
long long temp = [[currDict objectForKey:@"ParentPSN"] longLongValue];
[currDict release];
long long hi = (temp >> 32) & 0x00000000FFFFFFFFLL;
long long lo = (temp >> 0) & 0x00000000FFFFFFFFLL;
ProcessSerialNumber parentPSN = {(unsigned long)hi, (unsigned long)lo};

// Get info on the launching process
NSDictionary* parentDict = (NSDictionary*)ProcessInformationCopyDictionary (&parentPSN, kProcessDictionaryIncludeAllInformationMask);

// Test the creator code of the launching app
NSString *parentName = [[parentDict objectForKey: kIOBundleNameKey] retain];
[parentDict release];

return [parentName autorelease] ;

return nil;
To get the parent process name in the Unix sense:
