- Declared in:
- Foundation/NSProcessInfo.h
Availability: OpenStep
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.
+ (
NSProcessInfo*)
processInfo;
Availability: OpenStep
Returns the shared NSProcessInfo object for the
current process.
- (
NSUInteger)
activeProcessorCount;
Availability: MacOS-X 10.5.0
Not implemented
- (
NSArray*)
arguments;
Availability: OpenStep
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.
- (
NSDictionary*)
environment;
Availability: OpenStep
Returns a dictionary giving the environment
variables which were provided for the process to
use.
- (
NSString*)
globallyUniqueString;
Availability: OpenStep
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.
- (
NSString*)
hostName;
Availability: OpenStep
Returns the name of the machine on which this
process is running.
- (
NSUInteger)
operatingSystem;
Availability: MacOS-X 10.0.0
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
- (
NSString*)
operatingSystemName;
Availability: MacOS-X 10.0.0
Return a human readable string representing the
operating system type.
The supported types
are -

Availability: MacOS-X 10.2.0
Description forthcoming.
- (unsigned long long)
physicalMemory;
Availability: MacOS-X 10.5.0

- (int)
processIdentifier;
Availability: MacOS-X 10.0.0
Returns the process identifier number which
uniquely identifies this process on this machine.
- (
NSString*)
processName;
Availability: OpenStep
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).
- (
NSUInteger)
processorCount;
Availability: MacOS-X 10.5.0
Not implemented
- (void)
setProcessName: (
NSString*)newName;
Availability: OpenStep
Change the name of the current process to
newName.
- Declared in:
- Foundation/NSProcessInfo.h
Availability: Base
Likely to be changed/moved/removed at 1.17.0
Provides GNUstep-specific methods for controlled
debug logging (a GNUstep facility) and an
internal/developer-related method.
Method summary
+ (void)
initializeWithArguments: (char**)argv
count: (int)argc
environment: (char**)env;
Availability: Base
Likely to be changed/moved/removed at 1.17.0
Obsolete... the
GSInitializeProcess()
function has the same effect and can be called
more easily from other languages (particularly C).
- (BOOL)
setLogFile: (
NSString*)path;
Availability: Base
Likely to be changed/moved/removed at 1.17.0
Set the file to which NSLog output should be directed.
Returns YES on success,
NO on failure.
By default
logging goes to standard error.
