site_archiver@lists.apple.com Delivered-To: darwin-dev@lists.apple.com I am seeing a kIOReturnIPCError form an IOUserClient down call (i.e. from my app into the kernel) when I have a structure that is over 4K (4096) bytes in size. Is this a hard limit? Can I change this limit? I have some I/O through the user client that I would like to take a larger buffer (16K). Thanks for any tips, ...Duane _______________________________________________ Do not post admin requests to the list. They will be ignored.
