Why use api's rather than system calls?
System calls are platform-dependent, while using abstracted APIs allows your programs to run on multiple platforms, which is a primary benefit of Java. You should minimize the use of system calls when possible, because those will not be portable across platforms.
What are API calls used for?
"API calls" have no specific question; the term APIsimply means application programming interface, and to call an API simply means to invoke a function (or subroutine) from a computer program.Each API call is different in how it is called (e.g. does it require any parameters, and of so, which), when (e.g. can it be called at any time and under all circumstances), what it does and what it returns to the caller.API functions serving closely related purposes are often grouped together into an API.Take this hypothetical example: One API provides services for rounding numbers: one function of this API rounds numbers to the nearest whole number, another function that belongs to the same API rounds numbers to the nearest hundredth.The purpose of API is unlimited. Examples of API include API to allocate, manage and return memory from a heap, API to create, manage and delete files and folders on a hard disk, API to get and set the current time, API to draw lines and other geometric shapes, etc, etc.
Does API 6D meet or exceed API 598?
API 6D exceeds API 598 in both pressure and duration.
API 5L Vs API X70?
API X70 is one of line pipe grade family define by API 5L specification
What is API?
API is an Application Programming Interface.It is an interface that defines the ways by which an application program may request services from libraries and/or operating systems.An API determines the vocabulary and calling conventions the programmer should employ to use the services. It may include specifications for routines, data structures, object classes, and protocols used to communicate between the requesting software and the library.An API itself is largely abstract in that it specifies an interface and controls the behavior of the objects specified in that interface. The software that provides the functionality described by an API is said to be an implementation of the API. An API is typically defined in terms of the programming language used to build the application.The API initialism may sometimes be used as a reference, not only to the full interface, but also to one function, or even a set of multiple APIs provided by an organization. Thus, the scope of meaning is usually determined by the person or document that communicates the information.

What are System calls for file creation in unix?
Those API calls would be in section 2 of the manual: open/close/fopen/fclose/freopen
Why do you prefer using API over system call to execute services or routines of operating system?
simplicity & portability, especially if POSIX API is used as many totally different OSs support this API. using native OS calls would result in nonportable code.
If your 4 wheeler calls for oil api-sf-sg is api cj-4 sm better?
Yes. sm is better and newer than sf or sg.
Which man page section refers to system calls?
There are several 'man' sections for system calls. The basic system calls for the C api are in section 2, which is pretty much the default. Others may be in 3C, 3S, etc., depending on the type of functionality they have. For example, a lot of the string related functions are in 3S. Anything that has an admin type of API requirement might be in sections 5 and 8, or 8m, etc., depending on the OS type.
What is difference between API 6D and API 598?
The pressure test for API 598 is slightly less pressure and less duration than API 6D. API 6D is specifically for pipeline valves.

What is developing a system?
Im pretty sure that is an API.
How does rootkit running in user mode normally hide?
A+ pg. 1052: A rootkit running in user mode intercepts the API calls between the time when the API retrieves the data and when it is displayed in a window.
What is jdbc-odbc bridge?
jdbc-odbc bridge is a jdbc driver required to connect java application to the specified database. Using this driver the java calls are converted to the odbc calls and then are referred to the database. Since odbc driver are the implemetation of the API written in C language. As in the case of this driver the API is provided by Sun MicroSystem itself and the implementation of these API is done by the Database Vendors.
Difference system call api and system call subroutine?
Application Programming Interface (API) is a set of functions, objects, protocols or datastructures for the support of application development for developers/programmers. It is actually a kind of function definition which specifies how to make available of a specific service of the system/OS. The API's are available from library or from Operating system itself. Whenever a programmer need a specific service from OS, he/she can use appropriate API to do that.Processes in a system are run in different modes, process run in user mode have no access to the privileged instructions. If they want perform any privileged instructions or need of any services they request kernal for that service through System Calls. System calls are made by way of software interrupt. This is actually a request for the service whereas API is a function description that can be used by the programmer for his programs, its like a tool used to obtain a specific task in his programs.A system call is generally made by an application programme to the operating system.this instruction interrupts the current executing programme and transfers control to the interrupt routine.The contents of the executing programme are saved.After the interrupt routine finishes its function,control is transferred back to the executing programme.
What is a system development key?
Im pretty sure that is an API.
