I have written a kernel driver.Now want to talk to it through a userclient.My user space application is a cocoa application which calls IOServiceOpen() to establish a connection with the userclient.The call too IOServiceOpen fails and returning a value of hex value of 0xe00002c7 (-536870201 in decimal).But the API's IOMasterPort(),IOServiceMatching() & IOServiceGetMatchingServices() are returning success.Can anybody help me out in this matter.
The info.plist file was corrupted. I created a new one with "IOUserClientClass" and its name as key-value pair. Now it works.I am able to send data to the driver from my userspace program :-) .I need to send data back to my user space cocoa app from my driver.How can this be done?
