The system call interface of a kernel is the set of all implemented and available system calls in a kernel. In the Linux kernel, various subsystems, such as the Direct Rendering Manager (DRM), define their own system calls, all of which are part of the system call interface. Various issues with the organization of the Linux kernel system calls ...
System call. A high-level overview of the Linux kernel's system call interface, which handles communication between its various components and the userspace. In computing, a system call (commonly abbreviated to syscall) is the programmatic way in which a computer program requests a service from the operating system [a] on which it is executed.
The set of the Linux kernel API that regards the interfaces exposed to user applications is fundamentally composed of UNIX and Linux-specific system calls. [197] A system call is an entry point into the Linux kernel. [198] For example, among the Linux-specific ones there is the family of the clone(2) system calls. [199]
io_uring (previously known as aioring) is a Linux kernel system call interface for storage device asynchronous I/O operations addressing performance issues with similar interfaces provided by functions like read() / write() or aio_read() / aio_write() etc. for operations on data accessed by file descriptors. [1][2]: 2.
covers current UNIX ® standards (POSIX.1-2001 /SUSv3 and POSIX.1-2008 /SUSv4 ) Published. 2010 (No Starch Press) Pages. 1512. ISBN. 978-1-59327-220-3. The Linux Programming Interface: A Linux and UNIX System Programming Handbook is a book written by Michael Kerrisk, which documents the APIs of the Linux kernel and the GNU C Library (glibc).
The GNU C library, an implementation of the C standard library, works as a wrapper for the system calls of the Linux kernel necessary to the kernel-userspace interface, the toolchain is a broad collection of programming tools vital to Linux development (including the compilers used to build the Linux kernel itself), and the coreutils implement ...
fork (system call) In computing, particularly in the context of the Unix operating system and its workalikes, fork is an operation whereby a process creates a copy of itself. It is an interface which is required for compliance with the POSIX and Single UNIX Specification standards. It is usually implemented as a C standard library wrapper to ...
The calling convention of the System V AMD64 ABI is followed on Solaris, Linux, FreeBSD, macOS, [26] and is the de facto standard among Unix and Unix-like operating systems. The OpenVMS Calling Standard on x86-64 is based on the System V ABI with some extensions needed for backwards compatibility. [ 27 ]
