This book describes the C programming language as implemented by the Open Watcom C16 and C32 compilers for 80x86-based processors. Open Watcom C16 and C32 are implementations of ANSI/ISO 9899:1990 Programming Language C. The standard was developed by the ANSI X3J11 Technical Committee on the C Programming Language. In addition to the full C language standard, the compiler supports numerous extensions for the 80x86 environment.
This book is intended to be a reference manual and hence a precise description of the C language. It also attempts to remain readable by ordinary humans. When new concepts are introduced, examples are given to provide clarity.
Since C is a programming language that is supposed to aid programmers trying to write portable programs, this book points out those areas of the language that may vary from one system to another. Where possible, the probable behavior of other C compilers is mentioned.
