You should ensure that you complete the LMX_HOSTID structure correctly and return the appropriate error code, as shown in the following example.
| Code Block | ||
|---|---|---|
| ||
LMX_STATUS LMX_CALLBACK MyHostidCallback(LMX_HOSTID *pHostid, int *npHostids) |
...
{ |
...
printf("My HostID called\n"); |
...
/* Set the length of the data of this HostID. */ |
...
/* Its length can be up to LMX_MAX_SHORT_STRING_LENGTH */ |
...
strcpy(pHostid[0].szValue, "abcd"); |
...
/* Set optional description. */ |
...
/* Its length can be up to LMX_MAX_SHORT_STRING_LENGTH */ |
...
strcpy(pHostid[0].szDescription, "my HostID"); |
...
/* Now we do it once more for a 2nd HostID. */ |
...
strcpy(pHostid[1].szValue, "12345"); |
...
strcpy(pHostid[1].szDescription, "my HostID2"); |
...
/* Set that we return 2 custom HostIDs. */ |
...
*npHostids = 2; |
...
/* The function must return either LMX_SUCCESS or LMX_UNKNOWN_ERROR. */ |
...
return LMX_SUCCESS; |
...
/* return LMX_UNKNOWN_ERROR; */ |
...
} |
The same callback function is also required to use custom HostIDs on a license server. In lmxserverconf.c you can set the custom HostID callback function to create licenses that are locked to a license server with a custom HostID.
