Programmatically put a Mac into sleep

Question

I can\'t find any instructions how to put a Mac programmatically into sleep mode (in Objective-C). I\'m sure it should be only one line, but could you give me a hint?

Answer 1

You can use AppleScript

NSAppleScript *script = [[NSAppleScript alloc] initWithSource:@"tell application \"System Events\" to sleep"];
NSDictionary *errorInfo;
[script executeAndReturnError:&errorInfo];
[script release];
