This appendix lists the function prototypes contained in each of the header files supplied with most C compilers. Functions that have an asterisk after them were covered in this book.

The functions are listed alphabetically. Following each name and header file is the complete prototype. Notice that the header file prototypes use a notation different from that used in this book. For each parameter a function takes, only the type is given in the prototype; no parameter name is included. Here are two examples:

int func1(int, int *);int func1(int x, int *y);
