Returns the shared NSProcessInfo object for the current process.

Not implemented

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.

Returns a dictionary giving the environment variables which were provided for the process to use.

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.

Returns the name of the machine on which this process is running.

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

Return a human readable string representing the operating system type.
The supported types are -

• GSBeperatingSystem - Used for Be-OS (probably obsolete)
• GSCygwinOperatingSystem - cygwin unix-like environment

Description forthcoming.

Not implemented

Returns the process identifier number which uniquely identifies this process on this machine.

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).

Not implemented

Change the name of the current process to newName.

Fallback/override method. The developer must call this method to initialize the NSProcessInfo system if none of the system-specific hacks to auto-initialize it are working.
It is also safe to call this method to override the effects of the automatic initialisation, which some applications may need to do when using GNUstep libraries embedded within other frameworks.

Returns a indication of whether debug logging is enabled. This returns YES unless a call to -setDebugLoggingEnabled: has been used to turn logging off.

This method returns a set of debug levels set using the --GNU-Debug=... command line option and/or the GNU-Debug user default.
You can modify this set to change the debug logging under your programs control... but such modifications are not thread-safe.

This method permits you to turn all debug logging on or off without modifying the set of debug levels in use.

Set the file to which NSLog output should be directed.
Returns YES on success, NO on failure.
By default logging goes to standard error.
