[ts-7000] Easy 32-bit read operation question

["alexdavisspecial" <>]

Hey group!
I currently have this JNI write byte operation:

JNIEXPORT jint JNICALL 
Java_com_nextbus_signcontroller_mvc_TechnologicHAL_mmapWriteByte
  (JNIEnv *env, jclass obj, jint address, jbyte value)
{
    /* Use mmap() to map memory, then write byte to address */
    off_t page;
    volatile unsigned char *start;
    int ret;
    int fd;

    fd = open("/dev/mem", O_RDWR);
    if (fd == -1) return -1;
    page = address & PAGE_MASK;
    start = (unsigned char*)
        mmap(0,getpagesize(),PROT_READ|PROT_WRITE,MAP_SHARED,fd,page);
    if (start == MAP_FAILED) {
        close(fd);
        return -1;
    }
    *(start + (ADDR_MASK & address)) = value;
    ret = munmap((void*)start,getpagesize());
    close(fd);
    return ret;
}

And I want to make it 32-bit. Is it as easy as making the 'value' parameter a 
'jint'?

Thanks so much!
Alex
