LMX_STATUS LMX_Hostid |

( LMX_HANDLE LmxHandle, |
...
LMX_HOSTID_TYPE eHostidType, |

LMX_HOSTID *lpHostid, |

int *npHostids |

); |
Parameters
LmxHandle
[in/out] LM-X handle.

When using LMX_HOSTID_ALL, all HostIDs are returned, with the HostID type prefixing the HostID; for example, "ETHERNET=0123456789012345,USERNAME=MyUserName,HOSTNAME=MyHostName,...", etc. Otherwise, the HostID is returned without the HostID type prefixing the HostID; for example, for HostID type LMX_HOSTID_ETHERNET, the string in the preceding example would appear as "0123456789012345".
Examples:

LMX_HOSTID Hostids[LMX_MAX_HOSTIDS]; |
...
int nHostids; |
...
int i, j; |
...
LMX_Hostid(LmxHandle, LMX_HOSTID_ETHERNET, Hostid, &nHostids); |
...
for (i = 0; i < nHostids; i++) |
...
printf("Hostid: %s\n", Hostid[i].szValue); |
To make use of custom HostIDs, you must set a callback function using LMX_SetOption with the flag LMX_OPT_CUSTOM_HOSTID_FUNCTION.
