Built-in Functions

Abstract

This chapter describes the functions that are provided with C compilers. Both the standard ANSI functions and microcontroller extended functions are covered. Math functions, dynamic memory functions, memory manipulation functions, and text I/O functions are all included.

The text I/O functions include the newer cin/cout-style I/O. This chapter also describes the use of variable argument lists and the functions used to implement that language feature. The embedded concepts of data EEPROM, watchdog timers, and multiple clock speeds are described. Standard header files and constants are also a part of this chapter. The special way getenv() is used for microcontrollers is detailed.
