IOPMAssertionCreateWithName() doesn't seem to exist anywhere
(google knows nothing about it). IOPMAssertionCreate() doesn't seem
to exist in pre-10.5 and since I see no need to restrict to 10.5,
that doesn't work for me.
* Prefer IOPMAssertionCreateWithName(), which lets you pass a
string describing the purpose of the assertion (for debugging &
diagnostic use for Apple & yourself) over the vanilla
IOPMASsertionCreate. If you invoke IOPMAssertionCreate from
multiple points in your code; naming the assertions differently
will help identify leaks.
As I said, IOPMAssertionCreateWithName() doesn't seem to exist.
Xcode doesn't know about it, google doesn't know about it, I can't
find it on my system:
$ find /System/Library/Frameworks -name '*.h' -print0|xargs -0 grep
IOPMAssertionCreateWithName
prints nothing.
Try IOPMAssertionCreate(); it's defined in the 10.4 and 10.5 SDK in
IOKit.framework/Versions/A/Headers/pwr_mgt/IOPMLib.h. I think 10.4
was the first place it was published as non-private.
and it only returned results in the 10.5 SDK [with no results for
IOPMAssertionCreateWithName].
