memcmp()                 Compare Characters from Two Buffers
 
 #include   <memory.h>                   Required for declarations only
 #include   <string.h>                   Use either string.h or memory.h
 
 int        memcmp(buf1,buf2,cnt);
 char       *buf1;                       First buffer
 char       *buf2;                       Second buffer
 unsigned   cnt;                         Number of characters
 
    memcmp() compares 'cnt' characters of 'buf1' and 'buf2'
    lexicographically ('a' is less than 'b', 'b' is equal to 'b', and 'c'
    is greater than 'b').
 
    Returns:    A value indicating the relationship between the two
                buffers:
 
                         Result       Value Returned
                    'buf1' < 'buf2'         < 0
                    'buf1' == 'buf2'          0
                    'buf1' > 'buf2'         > 0
 
      Notes:    Case matters: 'a' does not equal 'A'.
 
  -------------------------------- Example ---------------------------------
 
    The following statement compares the first 100 bytes of 'buffr1' and
    'buffr2'.
 
          #include <memory.h>
 
          char buffr1[100], buffr2[100];
          int comp;
 
          main()
          {
              comp = memcmp(buffr1,buffr2,100);
          }
