Tizen OS Upgrade Progress Interface

※ When you develop OS upgrade UI app, you can read the current progress with these interfaces

RO progress

1. Current progress(%)
   • File path : /tmp/upgrade/ro_progress
   • Value
     • 0~100 : current progress(%)
     • -1 : Request to terminate RO progress UI app

void print_ro_progress(void)
{
    int progress = -1;
    FILE *fp = NULL;

    fp = fopen("/tmp/upgrade/ro_progress", "r");
    if (fp) {
        if (fscanf(fp, "%d", &progress) < 1)
            LOG("Failed to read RO upgrade progress");
    }

    if (progress == -1)
        LOG("RO progress is finished");
    else
        LOG("RO progress : %d percent", progress);
}

RW progress

1. The number of executed RW upgrade scripts
   • File path : /tmp/upgrade/progress
2. The number of RW upgrade scripts
   • File path : /tmp/upgrade/total

void print_rw_progress(void)
{
    int executed = -1;
    int total = -1;
    FILE *fp = NULL;

    fp = fopen("/tmp/upgrade/progress", "r");
    if (fp) {
        if (fscanf(fp, "%d", &executed) < 1)
            LOG("Failed to read the number of executed scripts");
    }

    fp = fopen("/tmp/upgrade/total", "r");
    if (fp) {
        if (fscanf(fp, "%d", &total) < 1)
            LOG("Failed to read the number of RW upgrade scripts");
    }

    LOG("RW progress : %d/%d", executed, total);
}
