Hi,
I am looking for either an API or a program to place my monitor, but not my computer / hard drive to sleep. This would be similar to "xset dpms force off" in Linux. Thanks for any assistance.

Thanks for the pointer. The above funcction seems to be most promising for what I want todo. However, I created a small program that used it, but it did not seem to do anything. Below is the program. Do you see anything wrong w/ it?
#import <CoreServices/CoreServices.h>
/*
- $ gcc -c setsleep.m
- $ gcc -o setsleep setsleep.o -lobjc -framework CoreServices
- $ ./setsleep */
int main(int argc, char * argv[]) { SetDimSuspendState(1);
return 0;
}

I don't know, maybe you need to call DimmingControl(true) first or something. Did you manage to find any actual documentation for those calls?

I guess I should have looked first:
*** begin doc *** http://developer.apple.com/documentation/Carbon/Reference/Power_Manager/01powermanager/function_group_7.html#//apple_ref/c/func/SetDimSuspendState
Availability
Supported in Carbon. Available in CarbonLib 1.0 and later when PowerMgr 1.1 or later is present. Available in Mac OS X 10.0 and later.
Header: Power.h
Carbon Porting Notes
Calling this function on Mac OS X does nothing. Although available through Carbon on Mac OS X, SetDimSuspendState is unimplemented. *** end doc ***
The part about being unimplemented in OS X seems significant...:{
