cat(1) uses read(2)/write(2) unless -v is specified, in which case it uses
getc(3).

int
cat(fi, fname)
FILE *fi;
char *fname;
{
        register int fi_desc;
        register int nitems;

        fi_desc = fileno(fi);

        /*
         * While not end of file, copy blocks to stdout. 
         */

        while ((nitems=read(fi_desc,buffer,BUFSIZ))  > 0) {
                if ((errnbr = write(1,buffer,(unsigned)nitems)) != nitems) {

...

vcat(fi)
FILE    *fi;
{
        register int c;

        while ((c = getc(fi)) != EOF) 
        {
                /*
                 * For non-printable and non-cntrl  chars, use the "M-x" notation.
                 */
                if (!ISPRINT(c, wp) &&
                    !iscntrl(c) && !ISSET2(c) && !ISSET3(c))
                        {
                        putchar('M');
                        putchar('-');
                        c-= 0200;
                        }
