Software documentation for the NSProcessInfo class
Foundation/NSProcessInfo.h
Instances of this class encapsulate information on the current process. For example, you can get the arguments, environment variables, host name, or process name. There is only one instance per process, for obvious reasons, and it may be obtained through the +processInfo method.
processInfo
Returns the shared NSProcessInfo object for the current process.
activeProcessorCount
Not implemented
arguments
Returns an array containing the arguments supplied to start this process.
NB. In GNUstep, any arguments of the form --GNU-Debug=... are not included in this array... they are part of the debug mechanism, and are hidden so that setting debug variables will not effect the normal operation of the program.
Please note, the special `--GNU-Debug=...` syntax differs from that which is used to specify values for the NSUserDefaults system.
User defaults are set on the command line by specifying the default name (with a leading hyphen) as one argument, and the default value as the following argument. The arguments used to set user defaults are present in the array returned by this method.

environment
Returns a dictionary giving the environment variables which were provided for the process to use.
globallyUniqueString
Returns a string which may be used as a globally unique identifier.
The string contains the host name, the process ID, a timestamp and a counter.
The first three values identify the process in which the string is generated, while the fourth ensures that multiple strings generated within the same process are unique.
hostName
Returns the name of the machine on which this process is running.
operatingSystem
Return a number representing the operating system type.
The known types are listed in the header file, but not all of the listed types are actually implemented... some are present for MacOS-X compatibility only.
NSWindowsNTOperatingSystem - used for Windows NT, and later
NSWindows95OperatingSystem - probably never to be implemented
NSSolarisOperatingSystem - used for Sun Solaris
NSHPUXOperatingSystem - used for HP/UX
NSMACHOperatingSystem - MacOSX and perhaps Hurd in future?
NSSunOSOperatingSystem - Used for Sun Sun/OS
NSOSF1OperatingSystem - Used for OSF/1 (probably obsolete)
GSGNULinuxOperatingSystem - the GNUstep 'standard'
GSBSDOperatingSystem - BSD derived operating systems
GSBeperatingSystem - Used for Be-OS (probably obsolete)
GSCygwinOperatingSystem - cygwin unix-like environment
operatingSystemName
Return a human readable string representing the operating system type.
The supported types are - NSWindowsNTOperatingSystem - used for Windows NT, and later NSWindows95OperatingSystem - probably never to be implemented NSSolarisOperatingSystem - used for Sun Solaris NSHPUXOperatingSystem - used for HP/UX NSMACHOperatingSystem - MacOSX and perhaps Hurd in future?

physicalMemory
Not implemented
processIdentifier
Returns the process identifier number which uniquely identifies this process on this machine.
processName
Returns the process name for this process. This may have been set using the -setProcessName: method, or may be the default process name (the file name of the binary being executed).
processorCount
Not implemented
setProcessName:
newName
Change the name of the current process to newName.
systemUptime

Software documentation for the NSProcessInfo(GNUstep) category
Foundation/NSProcessInfo.h
Provides GNUstep-specific methods for controlled debug logging (a GNUstep facility) and an internal/developer-related method.
initializeWithArguments:
argv
count:
argc
environment:
env
Obsolete... the GSInitializeProcess() function has the same effect and can be called more easily from other languages (particularly C).
androidCacheDir
Description forthcoming.
androidContext
Description forthcoming.
androidFilesDir
Description forthcoming.
setLogFile:
path
Set the file to which NSLog output should be directed.
Returns `YES` on success, `NO` on failure.
By default logging goes to standard error.
