The buffer manipulation routines are used to work on memory buffers on a character-by-character basis. A buffer is an array of characters like a string, however, a buffer is usually not terminated with a null character (\0). For this reason, these routines require a buffer length or count argument.
All of these routines are implemented as functions. Function prototypes are included in the STRING.H include file.
