API – application program interface

Ankit.singhal85@yahoo.com — Thu, 05 Jun 2014 04:41:31 +0000

API, an abbreviation of application program interface, is a set of routines, protocols, and tools for building software applications. The API specifies how software components should interact and are used when programming graphical user interface (GUI) components. A good API makes it easier to develop a program by providing all the building blocks. A programmer then puts the blocks together.

Character Driver(Completion)

Ankit.singhal85@yahoo.com — Thu, 05 Jun 2014 04:26:28 +0000

#for the another synchroniztion technique.....COMPLETION....here in the end of the devwrite i make a call for the completion and in the devread in the starting i call wait_for_completion() and in the end i call complete()....it work fine for me.....
