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.
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 ...
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).
ioctl. In computing, ioctl (an abbreviation of input/output control) is a system call for device-specific input/output operations and other operations which cannot be expressed by regular file semantics. It takes a parameter specifying a request code; the effect of a call depends completely on the request code.
write (system call) The write is one of the most basic routines provided by a Unix-like operating system kernel. It writes data from a buffer declared by the user to a given device, such as a file. This is the primary way to output data from a program by directly using a system call. The destination is identified by a numeric code.
