One way to check the dongle is by ensuring that LMX_HOSTID_DONGLE_HASPHL HostID is in use and, if so, comparing the HostID value against the last known good value, as demonstrated in the following example.
| Code Block | ||
|---|---|---|
| ||
int i; |
...
LMX_FEATURE_INFO FI; |
...
LMX_HOSTID LmxHostid[LMX_MAX_HOSTIDS]; |
...
int nHostids; |
...
LMX_GetFeatureInfo(LmxHandle, "my_app", &FI); |
...
/* Go through each hostid used for this particular feature */ |
...
for (i = 0; i < FI.nClientLicenseHostids; i++) |
...
{ |
...
/* See if the hostid is a dongle hostid */ |
...
if (FI.ClientLicenseHostid[i].nHostidType == LMX_HOSTID_DONGLE_HASPHL) |
...
{ |
...
/* See if hostid function reports the same value as we used when checking out the license */ |
...
if (LMX_Hostid(LmxHandle, LMX_HOSTID_DONGLE_HASPHL, LmxHostid, &nHostids)!= LMX_SUCCESS) |
...
return BAD_DONGLE; |
...
if (nHostid != 1) |
...
return BAD_DONGLE; |
...
/* Compare if the hostid at checkout time matches the hostid at present time */ |
...
if (strcmp(FI.ClientLicenseHostid[0].szValue, LmxHostID[0].szValue) != 0) |
...
return BAD_DONGLE; |
...
} |
...
} |
This check should preferably be done every few minutes to ensure that users do not move the dongle to other workstations and overuse standalone licenses.
