Last blog we introduced the thread synchronization through Cyclicbarrier, but the problem with this approach is that if a large task runs 2 threads to complete, if the thread 2 takes more than 1 twice times the thread, the thread 1 completes and waits for the thread 2 to complete, and the waiting process thread 1 cannot be reused. Now that we're ready to solve this problem, we want thread 1 to help thread 2 complete a portion of the task after completing its own task. Java7 as a

Today a friend went to a good foreign company to interview the Linux development position, the interviewer has a following topic:Give the following C program, using GCC to compile under Linux: 1234567891011121314 #include "stdio.h" # Include "Sys/types.h" #include "unistd.h" int main () { NBSP;NBSP;NBSP;NBSP; pid_t pid1; NBSP;NBSP;NBSP;NBSP; pid_t Pid2; NBSP;NBSP;NBSP;NBSP; pid1 = fork (); NBSP;NBSP;NBSP;NBSP; pid2 =

When the thread calls fork, a copy of the entire process address space is created for the child process. The child processes inherit the state of all mutexes, read-write locks, and condition variables from the parent process by inheriting copies of the entire address space. If the parent process contains more than one thread, the child process will need to clear the state of the lock if it is not immediately called Exec, after the

In Unix programming, learning to use fork and signal is quite basic.Fork () and signal are often used in daemon resident programs.A4c. tty/yact/chdrv these Chinese terminal programs are also useful, suchMozilla, Apache, squid, and other large programs are almost always used.Although programming in UNIX does not require much thread functionalityAlmost all jobs already exist. Pthread is the thread function library on Linux. If youIt is necessary to writ

System ();The system () function calls the shell program to execute the command (low efficiency), which is equivalent to fork (), then Execve (); Features: The original process and the sub-process each run, and the original process needs to wait for the child process to run, and then continue;1.

Fork () can be imagined as a symbol of power, and power can sometimes be imagined as a symbol of destruction. Therefore, be careful when your system is disorganized due to fork (). This is not to say never to Touch fork (), you just need to be cautious.Fork () is how Unix starts a new process. Basically, it works like this: the parent process (the one that alread
