strace is a diagnostic, debugging and instructional userspace utility for Linux.It is used to monitor and tamper with interactions between processes and the Linux kernel, which include system calls, signal deliveries, and changes of process state.
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 ]
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.
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 are being publicly discussed. Issues have been pointed out by Andy Lutomirski, Michael Kerrisk and others.
The GNU C Library, commonly known as glibc, is the GNU Project implementation of the C standard library.It provides a wrapper around the system calls of the Linux kernel and other kernels for application use.
The calling convention of a given program's language may differ from the calling convention of the underlying platform, OS, or of some library being linked to. For example, on 32-bit Windows, operating system calls have the stdcall calling convention, whereas many C programs that run there use the cdecl calling convention. To accommodate these ...
OpenHarmony kernel abstract layer employs the third-party musl libc library and native APIs, providing support for the Portable Operating System Interface (POSIX) for Linux syscalls within the Linux kernel side and LiteOS kernel that is the inherent part of the original LiteOS design in POSIX API compatibility within multi-kernel Kernel ...
