n the recent years, Linux, a public domain, freely available Unix variant has attracted the people very much. Today`s complex production environments demands superior application performance. Linux is having extraordinary advantages such as : complete source code access, availability of exceptional optimization, testing tools. This book is to explore this facet of Linux.
Features
Explained Linux success stories with emphasis on facilities and tools available in Linux for SW development
Explains gcc (GNU) toolchain in detail, combining C and C++, C and Java, and C and Fortran in a lucid manner
How command line arguments can be handled by C/C++ programs with getopt, argp library are dealt
Discusses about environment variables and their management
System limits are explored with their implication of program performance
Explains about how assembly programming can be done under Linux
How to mix C and assembly, how system calls can be called from assembly, how modules can be developed in assembly and a bare boot (OS) program creation, are discussed in detail.
How static and dynamic libraries are developed and commissioned in Linux is explained and how Libtool can be used for library development is discussed
Dealt with Lex/Yacc tools, which are to be used in compiler development
Memory management, memory errors, Linux memory management, etc., are described with illustrative examples
A popularly used tool for detecting memory errors, Electric Fence, is explained with concept oriented examples
A chapter on Valgrind explained as to how memory can be checked for memory leaks, segment violations, analyze the cache performance in an illustrative manner
Describes memory mapping of files, especially for large files and the impact on program`s performance.
Gnu debugger (gdb) is detailed; gcov and gprof explains about profiling of a C program to improve its performance; make, rcs, SW tools explains how they can be used for SW development in practice.with concept oriented examples with special reference to Web enabled applications.
