A high-level comparison of in-kernel and kernel-to-userspace APIs and ABIs The Linux kernel and GNU C Library define the Linux API. After compilation, the binaries offer an ABI. Keeping this ABI stable over a long time is important for ISVs. In computer software, an application binary interface (ABI) is an interface between two binary program ...
An application programming interface (API) is a connection between computers or between computer programs. It is a type of software interface , offering a service to other pieces of software . [ 1 ]
Implementations may also be provided for non real-time operating systems, allowing the abstracted software to be developed and tested in a developer friendly desktop environment. In addition to the OS APIs, the OS abstraction layer project may also provide a hardware abstraction layer , designed to provide a portable interface to hardware ...
The Linux API is composed out of the system call interface of the Linux kernel, the GNU C Library (by GNU), libcgroup, [1] libdrm, libalsa and libevdev [2] (by freedesktop.org). Linux API vs. POSIX API. The Linux API includes the kernel–user space API, which allows code in user space to access system resources and services of the Linux kernel ...
Besides the most commonly used software library on Linux systems, the GNU C Library (glibc), there are numerous other libraries, such as SDL and Mesa. The C standard library is the library necessary to run programs written in C on a computer system, with the GNU C Library being the standard. It provides an implementation of the POSIX API, as ...
Binary compatibility is a major benefit when developing computer programs that are to be run on multiple OSes. Several Unix-based OSes, such as FreeBSD or NetBSD, offer binary compatibility with more popular OSes, such as Linux-derived ones, since most binary executables are not commonly distributed for such OSes.
C is commonly used on computer architectures that range from the largest supercomputers to the smallest microcontrollers and embedded systems. A successor to the programming language B, C was originally developed at Bell Labs by Ritchie between 1972 and 1973 to construct utilities running on Unix.
The book provides samples of code written in C, and learning exercises at the end of chapters. The author is a former writer for the Linux Weekly News [1] and the current maintainer for the Linux man pages project. [2] The Linux Programming Interface has been translated into several languages. [3]
