C Programming Help

Can anyone help with the following problem? I am trying to fix a problem in some code and, being a complete novice with no C programming experience I am probably missing the obvious. Below is the section that is causing the problem; the code compiles OK but when you run the program it is baulking at the for statement and skipping the rest of the code.

Code:

/* output the predefined special function registers                                      */
    sp = predef_sfr;
    for(i = 0; i < sizeof(predef_sfr) / sizeof(PREDEF_SFR); ++i)
    {   memset(outp, ' ', 79);
        if((sts = format_addr20(sp->sfr_addr, &outp[COL_PC])) < 0) /* put value in 1st 5 chars */
            return(sts);
        memcpy(&outp[20], sp->sfr_name, strlen(sp->sfr_name) );
        memcpy(&outp[54], "equ", 3);                            /* put SFR name in output    */
        outp[60] = '$';
        if((sts = format_addr20(sp->sfr_addr, &outp[61])) < 0)
            return(sts);
        outp[66] = '\0';                                     /* pull null termination in output */
        output_line(file_ptr_output, showhex, spacer_line, outp);
        ++sp;
    }

I think it is the second expression that is the cause of the problem where the loop should be comparing the loop counter with the total length of a structure. I'm sure that more info will be required to help understand the code snippet so just ask and I'll try to answer.

Thanks in advance.
