memory.h

The header file contains prototypes for functions that manipulate buffers in main memory where the size of the buffer is passed as an integer value. These functions are:

    memccpy()    memchr()    memcmp()    memicmp()
    memmove()    memcpy()    memset()
    movedata()  /* non ANSI */

These function copy, search, compare, and initialize buffers in memory.
