     bcopy(3C)                  DG/UX 4.30                   bcopy(3C)



     NAME
          bcopy - Copy bytes from one area to another.

     SYNOPSIS
          int bcopy(), length;
          char *source, *destination;
          bcopy(source, destination, length);



          where   source is the start of the area to copy from.

                  destination is the start of the area to copy the
                  bytes to.

                  length is the number of bytes to move.


     DESCRIPTION
          The bcopy function copies the number of bytes that you
          specify from one memory location to another; this function
          comes from the University of California Berkeley UNIX (BSD)
          system.  Unlike the memcpy function, the bcopy function
          behaves well if the two areas overlap.  Also note that the
          source and destination arguments are reversed as compared to
          memcpy's calling sequence.

     RETURNS
          The bcopy function returns no value.

     SEE ALSO
          See also the memcpy function.

     EXAMPLE
          The following program copies a string into a buffer and then
          prints it.
          /* Program test for the bcopy() function */

          #include <stdio.h>


          int bcopy();
          char buffer[80];

          main() {
              bcopy("Copy string with bcopy.\n", buffer, 24);
              fputs(buffer, stdout);
              return 0;
          }
