The idea is as follows: use file_get_contents () to get the content of the txt file, and then convert the obtained string to an array through explode. You can use the count () function to obtain the array length. 2. read api by line In a regular e

provider. The address of the socket also has a fixed format, but the format of the communication address is related to the domain of the socket, different communication domains have different communication addresses. Next we do the introduction:Af_unix Domain Communication address formatThis type of communication is primarily the communication between the different processes of the same computer, so the communication address is essentially a file path, except that the file is not an ordinary fi

In the 2.6 era, the steps for writing a linux system call are as follows: Compile the actual operation function Add macro definitions in linux/include/asm-i386/unistd. h#define __NR_myfunctioin 399 In linux/arch/i386/kernel/entry. S, add.long SYMBOL_NAME(myfunction) Compile the kernel Use _ syscall [1-6] (type, name, type, arg1) to call The corresponding macro definition file cannot be found at the corresponding location of the kernel in the latest version.

Debian, the kernel version may be different, so use a uname-r command to publish the book and then install it.Here, we can make a link file to/usr/src/linux-headers-$ (uname-r)/include/linux/, because Vmtools installation, will default to here to find the kernel header file, do a link we do not have to manually enter: Ln-s/usr/src/[email protected] (UNAME-R)/include/generated/uapi/linux/version.h/usr/src/[email protected] (uname-r )/include/

In Linux kernel, some constant must be used together by C code and javaser. When you use constant, you cannot give 0x1000ul a simple command because the hacker cannot view this item. However, C compiler can. So use this GCC feature. The constant that C compiler sees is 0x1000ul. In contrast, the number of referers is 0x1000. 6 /* Some constant macros are used in both between ER and 7 * C code. Therefore we cannot annotate them always 8 * 'Ul 'and other type sp
