This requires two pairs of messages (request and response) following receipt of theM_IOCTLmessage: the firstcopyin(9F)s the structure (address) and the secondcopyin(9F)the buffer (address.ad.addr). Two states are maintained and processed in this example:GETSTRUCTis for copying in the address...
IOCTL: usage example ioctl is used in communication with modules of Linux. Module: #include<linux/kernel.h>#include<linux/init.h>#include<linux/module.h>#include<linux/kdev_t.h>#include<linux/fs.h>#include<linux/cdev.h>#include<linux/device.h>#include<linux/slab.h>//kmalloc()#include...
本程序将锁的设置与测试都写成单独的子函数,程序首先在当前目录下建立了文件example_65,并写入了一个字符test lock到example_65文件中,然后对其进行文件记录锁的操作。 执行结果如下: $ ./6-5 lock can be set in fd set read lock,pid:15579
be sent by the Volume Shadow Copy Driver (volsnap.sys) during a hibernation request or before a crash dump. This IOCTL is sent to file system filter drivers, file system drivers, and other device drivers (storage filter drivers and storage drivers, for example) located below the file...

Note:The out-of-band data is a logically independent data channel that is delivered to the user independently of normal data; in addition, a signal is also sent because of the immediate attention required. Ctrl-C characters are an example. ...
For example, I ran: ./qemu-aarch64 /system/bin/wificond It gives me Unsupported ioctl: cmd=0xffffffffc0046209 Unsupported ioctl: cmd=0x40046205 Binder driver could not be opened. Terminating. So I think what I may want to do is to add that ioctl call manually. But the problem ...
