// shareDump() smoke test — TC 1.6.2
//
// Verifies the new SYS_SHARE_DUMP syscall (= 348) works end-to-end:
//   - publish a few mixed-type entries (int, float, str)
//   - call shareDump() — should log each entry + a summary
//   - verify the return value matches the number of live entries
//
// Expected log output (in order):
//   shareDump test: starting
//   shareDump test: published 4 entries (alpha=42, beta=1.5, gamma="hi", delta=99)
//   TCC: share[0] key="alpha" type=INT value=42
//   TCC: share[1] key="beta"  type=FLT value=1.500000
//   TCC: share[2] key="gamma" type=STR value="hi"
//   TCC: share[3] key="delta" type=INT value=99
//   TCC: shareDump: 4/32 live entries
//   shareDump test: live count=4

int main() {
    addLog("shareDump test: starting");

    // Clean any leftover entries from previous runs so the test is
    // deterministic. Shouldn't be needed on first ever boot.
    shareDelete("alpha");
    shareDelete("beta");
    shareDelete("gamma");
    shareDelete("delta");

    // Publish 4 mixed-type entries.
    shareSetInt("alpha", 42);
    shareSetFloat("beta", 1.5);
    char hi[8];
    strcpy(hi, "hi");
    shareSetStr("gamma", hi);
    shareSetInt("delta", 99);

    addLog("shareDump test: published 4 entries");

    int n = shareDump();
    addLog("shareDump test: live count=%d", n);

    return 0;
