[14] initramfs, also known as early user space, has been available since version 2.5.46 of the Linux kernel, [18] with the intent to replace as many functions as possible that previously the kernel would have performed during the startup process. Typical uses of early user space are to detect what device drivers are needed to load the main user ...
Similarly, the kill(1) command allows a user to send signals to processes. The raise(3) library function sends the specified signal to the current process. Exceptions such as division by zero, segmentation violation , and floating point exception will cause a core dump and terminate the program.
In the original design of the VMS operating system (1977), a copy operation with subsequent mutation of the content of a few specific addresses for the new process as in forking was considered risky. [citation needed] Errors in the current process state may be copied to a child process. Here, the metaphor of process spawning is used: each ...
Environment variables are part of the environment in which a process runs. For example, a running process can query the value of the TEMP environment variable to discover a suitable location to store temporary files, or the HOME or USERPROFILE variable to find the directory structure owned by the user running the process.
The concept behind a fork bomb — the processes continually replicate themselves, potentially causing a denial of service. In computing, a fork bomb (also called rabbit virus) is a denial-of-service (DoS) attack wherein a process continually replicates itself to deplete available system resources, slowing down or crashing the system due to resource starvation.
The Python plugin, which links against libpython, and allows one to invoke arbitrary Python scripts from inside the compiler. The aim is to allow GCC plugins to be written in Python. The MELT plugin provides a high-level Lisp-like language to extend GCC. [71] The support of plugins was once a contentious issue in 2007. [72] C++ transactional memory
An installation process that runs on a preset time or when a predefined condition transpires, as opposed to an installation process that starts explicitly on a user's command. For instance, a system administrator willing to install a later version of a computer program that is being used can schedule that installation to occur when that program ...
Bob Amstadt, the initial project leader, and Eric Youngdale started the Wine project in 1993 as a way to run Windows applications on Linux.It was inspired by two Sun Microsystems products, Wabi for the Solaris operating system, and the Public Windows Interface, [10] which was an attempt to get the Windows API fully reimplemented in the public domain as an ISO standard but rejected due to ...
