API Programming Series #1

Where does the API reside?

The bulk of the API functions are encapsulated in a set of DLLs -

, etc.

These DLLs form the core of the Windows OS and are present on all windows machines (At least the ones that are bootable :)). So unlike when you access a function from a third-party DLL, you don’t have to ship anything with your product when you use an API function. The effect this has on the distribution size and speed of your application has to be seen to be believed.

Note: In addition to the DLLs mentioned above certain other DLLS also find place in an API Programmers notebook. These are used to provide certain special functions like Encryption, Security related features etc. We will discuss some of them in later articles of this series.
