What is cl_kernels ?
by Jerry Krinock 31 Aug '12

31 Aug '12

I've received a few crash reports which have a library named cl_kernels loaded multiple times. I've seen this occasionally on my Mac too, an Intel Core i5 MacBook Air running Mac OS X 10.8.1. For example, here's part of a crash report from Mail.app: Binary Images: 0x104c91000 - 0x10502dff7 com.apple.mail (6.0 - 1482) <CD9A5D3C-C523-3FED-A558-B2FA10741B5F> … 0x10a9fd000 - 0x10a9feff3 +cl_kernels (???) <5B88BC0F-B34B-41C0-A250-8E04788A813D> cl_kernels 0x10aa17000 - 0x10aa18ff2 +cl_kernels (???) <3A3E5E9C-C9E7-4FDF-B6B9-E8B19DF5E1BC> cl_kernels 0x10aa1b000 - 0x10aa1bff3 +cl_kernels (???) <F6E8271A-1345-45F1-8E21-895B3AE116FB> cl_kernels 0x10aa5a000 - 0x10aa5bff3 +cl_kernels (???) <F5B043ED-91E2-4050-AA3C-E5097EE88580> cl_kernels … Why would a library need to be loaded 4 times in one app? In other crash reports, I've seen it up to 20 times. The .plist version of the crash report indicates that cl_kernels has attribute is_Apple=NO, but I've seen this on many Macs and I think maybe it *is* an Apple component. I don't find much information on cl_kernels in an internet search, other than in unexplained crash reports. Is it possible that cl_kernels spells "trouble"? _______________________________________________ Do not post admin requests to the list. They will be ignored.

lio_listio(2) was deprecated?
by Sid Moore 29 Aug '12

29 Aug '12

Hello, guys. It seems lio_listio(2) was deprecated in osx10.6/10.7/10.8. aio(4) lists this API, but no manpage interprets it. From the xnu source code, it seems it does exist. But when I try to call it in my program, -1 returned and errno was set to be 0. It is quite misunderstanding. If it is really deprecated, I think aio(4) should not show it. Am I correct? -- Best, Sid Moore _______________________________________________ Do not post admin requests to the list. They will be ignored.
