NPTL has been part of Red Hat Enterprise Linux since version 3, and in the Linux kernel since version 2.6. It is now a fully integrated part of the GNU C Library. [3] There exists a tracing tool for NPTL, called POSIX Thread Trace Tool . And an Open POSIX Test Suite was written for testing the NPTL library against the POSIX standard.
wait normally returns the exit status of the last job which terminated. It may also return 127 in the event that n specifies a non-existent job or zero if there were no jobs to wait for. Because wait needs to be aware of the job table of the current shell execution environment, it is usually implemented as a shell builtin .
appJar is a cross-platform Python library for developing GUIs (graphical user interfaces). [3] It can run on Linux , OS X , and Windows . It was conceived, and continues to be developed with educational use as its focus, [ 4 ] so is accompanied by comprehensive documentation, as well as easy-to-follow lessons.
In May 2015, the Linux kernel introduced a deadlock bug via Commit b0c29f79ecea that caused a hang in user applications. The bug affected many enterprise Linux distributions, including 3.x and 4.x kernels, and Red Hat Enterprise Linux version 5, 6 and 7, SUSE Linux 12 and Amazon Linux. [8] Futexes have been implemented in OpenBSD since 2016. [9]
A follow-up paper by Kogan and Petrank [20] provided a method for making wait-free algorithms fast and used this method to make the wait-free queue practically as fast as its lock-free counterpart. A subsequent paper by Timnat and Petrank [21] provided an automatic mechanism for generating wait-free data structures from lock-free ones. Thus ...
epoll is a Linux kernel system call for a scalable I/O event notification mechanism, first introduced in version 2.5.45 of the Linux kernel. [1] Its function is to monitor multiple file descriptors to see whether I/O is possible on any of them.
In computer operating systems, a process (or task) may wait for another process to complete its execution. In most systems, a parent process can create an independently executing child process . The parent process may then issue a wait system call , which suspends the execution of the parent process while the child executes.
Like the process method, but with lower overhead and without the data isolation that hampers coordination of the flows. Each LWP or thread itself uses traditional blocking synchronous I/O, which simplifies programming logic; this is a common paradigm used in many programming languages including Java and Rust.
