Synopsis

Any program worth its salt uses operating system services. Even a simple program, if practical, reads input and produces output. And, most applications have more complex needs. They need to find out the time, use the network, or start and communicate with other processes. Systems programming really means nothing more than writing software that uses these operating system services.UNIX Systems Programming for SVR4 gives you the nitty-gritty details on how UNIX interacts with applications. If you're writing an application from scratch, or if you're porting an application to any System V.4 platform, you need this book.The first part of the book presents simple functions and concepts supported by numerous code fragment examples and short demonstration programs. These examples become building blocks for the application program examples that appear later in the book to illustrate more advanced, complex functions.UNIX Systems Programming for SVR4 is thorough and complete and offers advice on:

• Working with low-level I/O routines and the standard I/O library
• Creating and deleting files and directories, changing file attributes, processing multiple input streams, file and record locking, and memory-mapped files
• Reading, printing, and setting the system time and date
• Determining who is logged in, times users log in and out, how to change a program's effective user ID or group ID, and writing set user ID programs
• Changing system configuration parameters for resource limits
• Creating processes, job control, and signal handling
• Using pipes, FIFOs, UNIX-domain sockets, message queues, semaphores, and shared memory for interprocess communication
• Reading and setting serial line characteristics including baud rate, echoing, and flow control
• Network programming with Berkeley sockets, Transport Layer Interface (TLI), a less popular but more flexible interface to network programming, and the data link provider interface

About this title

From the Back Cover

Any program worth its salt uses operating system services. Even the simplest program is likely to read input and produce output, and most real-world applications have more complex needs. They need to check the data and time, use the network, or start and communicate with other processes. "Systems programming" really means nothing more than writing software that uses these operating system services. UNIX Systems Programming for SVR4 gives you the nitty gritty details on how UNIX interacts with applications. Whether you're a student, system administrator, or software developer, if you're working on any System V Release 4 platform, you'll find this book indispensable. The book contains many extended examples on topics ranging from string manipulation to network programming. These examples can serve as starting points for your own applications. In addition to AT&T's release of SVR4, this book pays special attention to the three most important commercial UNIX implementations: Sun Microsystems' Solaris, Hewlett Packard's HP-UX 10, and Silicon Graphics' IRIX 5.3. It also includes notes on porting software from BSD UNIX to SVR4.

Synopsis

This book presents the details on how UNIX interacts with applications. If you're writing an application from scratch, or if you're porting an application to Solaris or to any other System V.4 platform, you may this book useful. It offers a complete explanation of all UNIX system calls and library routines to systems programming, working with I/O, files and directories, processing multiple input streams, file and record locking, and memory-mapped files. The reader will also learn about reading, printing, and setting the system time and date, determining who is logged in, and setting user and group ID. The book also shows how to change system configuration parameters for resource limits and how to create processes, job control, and signal handling. The work discusses interprocess communication, serial line characteristics, network programming with Berkeley sockets, Transport layer Interface (TLI), and the data link provider interface.
