UNIX System Interface Programming teaches you to write C programs with the most commonly used system and library calls in the Solaris 2.x operating system and Solaris 7 operating system.
|
It is designed for C programmers who will be writing applications that use the services of the Solaris 2.x operating system and Solaris 7 operating system. This course contains an introduction to the ANSI C, POSIX, and SVID-3 standards included in Solaris 2.x operating system and Solaris 7 operating system. It describes the use of the most popular system calls and library calls in the Solaris 2.x and Solaris 7 operating systems (including the standard I/O library and the low-level calls to use files and directories).
The course also covers the calls to create a new process and run a new program, signals, and Solaris 2.x operating system and Solaris 7 operating system inter-process communication facilities, including pipes, mmap, system VIPC, and sockets.
Upon completion of this course, you should be able to:
• Define the terms Portable Operating System Interface for Computer Environments (POSIX) and System V Interface Definition (SVID)
• Understand the relationship of the Solaris operating system to POSIX and SVID
• Write applications that perform basic file operations
• Use file and record locking
• Identify the differences between system and library functions
• Query and modify process attributes and resource limits
• Write applications that use memory-management facilities for dynamic memory allocation
• Understand the directory structure and write applications that can read directory hierarchies
• Compose applications that can generate other processes and exercise some control over the new processes
• Write applications that use the signal handling facilities and virtual memory facilities to improve performance and that exchange data through pipes, message queues, and shared memory
• Synchronize processes with the use of semaphores
• Write a simple client-server application using socket functions

Sun Microsystems
Sun ble grunnlagt med én eneste visjon som drivkraft. En visjon om datamaskiner som kommuniserte med hverandre uansett hvem som hadde laget dem. En visjon om teknikk som arbeider for deg, ikke motarbeider deg. Mens andre utviklet varemerkebeskyttede og proprietære løsninger, fokuserte vi på å hjelpe bedrifter inn i nettverksæraen. Som et resultat av dette er vi blitt dotten i .com. Vi leverer systemer og programvare som oppfyller kravene til skalerbarhet og påliteligheten som er nødvendig for å drive den elektroniske markedsplassen.
