I am new to Linux system programming and I came across API and ABI while reading Linux System Programming. Definition of API: An API defines the interfaces by which one piece of software communica...
Nice answer. Except this isn't what an ABI is. An ABI is a set of rules that determines calling convention, and rules for laying out structures. Pascal passes arguments on the stack in the reverse order from C applications, so pascal and C compilers do NOT compile to the same ABI. The respective standards for C and Pascal compilers implicitly ensure that this will be the case. C++ compilers ...
This is what wikipedia says: In computer software, an application binary interface (ABI) describes the low-level interface between an application (or any type of) program and the operating
ABI is basically how the function / procedures passes information to each other through registers (compiled form), where the return value stored (specify registers). In x86 or x86-x64 it is called ABI (Application binary interface). In ARM architecture, it is knows as EABI (extended application binary interface). The ABI from before 2000 is known as OABI (old application binary interface), now ...
What are the purposes of the ARM ABI and EABI? - Stack Overflow
The x32 ABI (32-bit pointers in long mode) is part of the x86-64 aka AMD64 ABI doc. See Chapter 10: ILP32 Programming Model. The GitLab repo auto-builds a PDF of the current x86-64 version, but not i386. See also the x86 tag wiki for other guides / references / links. The last version on Github was x86-64 version 1.0 draft (January 2018).
