what is meant by api with example
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 communicates with another at the source level.
Definition of ABI :
Whereas an API defines a source interface, an ABI defines the low-level binary interface between two or more pieces of software on a particular architecture. It defines how an application interacts with itself, how an application interacts with the kernel, and how an application interacts with libraries.
How can a program communicate at a source level ? What is a source level ? Is it related to source code in anyway? Or the source of the library gets included in the main program ?
The only difference I know is API is mostly used by programmers and ABI is mostly used by compiler.
The API is what humans use. We write source code. When we write a program and want to use some library function we write code like:
long howManyDecibels = 123L; int ok = livenMyHills( howManyDecibels);
and we needed to know that there is a method
livenMyHills(), which takes a long integer parameter. So as a Programming Interface it's all expressed in source code. The compiler turns this into executable instructions which conform to the implementation of this language on this particular operating system. And in this case result in some low level operations on an Audio unit. So particular bits and bytes are squirted at some hardware. So at runtime there's lots of Binary level action going on which we don't usually see.
What is the difference between API and ABI?, This article describe what API, ABI, and system calls are, and the difference between these words. Tagged with linux, api, abi, systemcalls. Answered February 26, 2018 · Author has 867 answers and 3.2M answer views. API (“application programming interface”) are constraints on source code. ABI (“application binary interface”) are constraints on object code. Typically, an API is described using a specific programming language, although some software systems (“frameworks” or “libraries”) offer multi-linguals APIs (e.g., many machine learning frameworks have both C++ and Python APIs).
API, ABI, and system call - DEV, Whereas an API defines a source interface, an ABI defines the low-level binary interface between two or more pieces of software on a particular architecture. Thus, the ABI may not detect a true injury, especially one in the lower extremities. The API, on the other hand, relies on the fact that the amount of atherosclerotic disease is usually symmetric between the two lower extremities or the two upper extremities.
Difference between API and ABI, 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� ABI comes from Application Binary Interface. It defines the binary expression of the functions and the data. It defines the more detailed specification than API. It's in charge of how many bytes do an argument takes and where the data should be set, for example, the top of stack or CPU's registers.
Application binary interface, Definition of ABI : Whereas an API defines a source interface, an ABI defines the low-level binary interface between two or more pieces of software on a particular � Definition of API : An API defines the interfaces by which one piece of software communicates with another at the source level. Definition of ABI : Whereas an API defines a source interface, an ABI defines the low-level binary interface between two or more pieces of software on a particular architecture.

The ankle-brachial pressure index (ABPI) or ankle-brachial index (ABI) is the ratio of the blood pressure at the ankle to the blood pressure in the upper arm (brachium). ). Compared to the arm, lower blood pressure in the leg suggests blocked arteries due to peripheral artery dise
ABI vs. API : programming, Question 1 Describe the difference between API and ABI services / functions. The Application Binary Interface (ABI) are the functions used to invoke kernel� KEY DIFFERENCE. Web service is a collection of open source protocols and standards used for exchanging data between systems or applications whereas API is a software interface that allows two applications to interact with each other without any user involvement.
02 Operating System Overview - Section 2 Operating , Difference between system software and application software � Computer Science MCQs Homepage � 3 Tier Database Architecture in DBMS � Data Bus, Address,� The best way to explain the difference between API and EDI is through a metaphor of two people communicating, instead of two computer systems. For the EDI (Electronic Data Interchange) scenario, imagine that I wrote out a paper note asking you to pick up some freight for me. I put that note into an envelope and hand it to you.
OS, operating systems, api, abi, isa, system programing, russian , in the long run is to ensure a proper versioning of the API and ABI. explain the difference Duration: 56:05 Posted: Jan 29, 2018 API vs Web Service. API and Web service serve as a means of communication. The only difference is that a Web service facilitates interaction between two machines over a network.
- by source level they mean something like include file to expose function definitions
- Also see stackoverflow.com/q/2171177/632951
- This is probably the best concise explanation of what an ABI is, that I have ever seen; gj!
- You guys need to decide whether this answer is concise or detailed. :)
- @jrok: Things can be concise and detailed they are not mutually exclusive.
- @LokiAstari, So isn't the ABI actually an API too?
- @Pacerier: They are both interfaces. But they are at different levels of abstraction. API is at the application developer level. ABI is at the compiler level (somewhere an application developer never goes).
- +1 for pointing out their mutual exclusiveness. For example, Java's introduction of the assert keyword is an API-incompatible yet ABI-compatible change docs.oracle.com/javase/7/docs/technotes/guides/language/… .
- You could add to your resources section "3.6. Incompatible Libraries" of tldp.org/HOWTO/Program-Library-HOWTO/shared-libraries.html, which lists what may cause an ABI change.
- Yours was the answer that was detailed enough to help me understand the difference between API and ABI. Thank you!
- this is a very succint explanation of difference between them, and in a very unique perspective.
