Dir Sir/Madam,
Our company are going to develop software on Mac OS X. And now I am
doing the research for it to confirm whether we can do it. Actually there
are many difficulties. With this letter I will ask a question about
Accessing Hardware from applications.
In the document "Hello Kernel: Creating a Kernel Extension With Project Builder"
you have give an example of kernel programming.The sample code is the
following:
#include <sys/systm.h>
#include <mach/mach_types.h>
kern_return_t HelloKernel_start (kmod_info_t * ki, void * d)
{
printf("KEXT has loaded!\n");
return KERN_SUCCESS;
}
kern_return_t HelloKernel_stop (kmod_info_t * ki, void * d)
{
printf("KEXT will be unloaded\n");
return KERN_SUCCESS;
}
And also I have done as the document "Packaging Your KEXT for
Distribution and Installation" says. My question is that how can I
access the module HelloKernel from application.
I have read your document "Accessing Hardware From Applications". But
I think the document is too difficult. So Can you give me an example of
accessing the HelloKernel from application?
Thanks!
yours sincerely
Ye Wenxi in Tokyo
