If the string is of the form UserName, the user name is expected to be found on the server specified by the servername parameter.
    `level` - Specifies the information level of the data.
    `flags` - Specifies a bitmask of flags. Currently, only the value LG_INCLUDE_INDIRECT is defined. If this bit is set, the function also returns the names of the local groups in which the user is indirectly a member (that is, the user has membership in a global group that is itself a member of one or more local groups).
    `bufptr` - Pointer to the buffer that receives the data. The format of this data depends on the value of the level parameter. This buffer is allocated by the system and must be freed using the NetApiBufferFree function. Note that you must free the buffer even if the function fails with ERROR_MORE_DATA.
    `prefmaxlen` - Specifies the preferred maximum length of returned data, in bytes. If you specify MAX_PREFERRED_LENGTH, the function allocates the amount of memory required for the data. If you specify another value in this parameter, it can restrict the number of bytes that the function returns. If the buffer size is insufficient to hold all entries, the function returns ERROR_MORE_DATA. For more information, see Network Management Function Buffers and Network Management Function Buffer Lengths.
    `entriesread` - Pointer to a value that receives the count of elements actually enumerated.
    `totalentries` - Pointer to a value that receives the total number of entries that could have been enumerated.

                    DsGetDC.PDOMAIN_CONTROLLER_INFO.ByReference DomainControllerInfo)

  The DsGetDcName function returns the name of a domain controller in a specified domain. This function accepts additional domain controller selection criteria to indicate preference for a domain controller with particular characteristics.

  Parameters:
    `ComputerName` - Pointer to a null-terminated string that specifies the name of the server to process this function. Typically, this parameter is NULL, which indicates that the local computer is used.
    `DomainName` - Pointer to a null-terminated string that specifies the name of the domain or application partition to query. This name can either be a DNS style name, for example, fabrikam.com, or a flat-style name, for example, Fabrikam. If a DNS style name is specified, the name may be specified with or without a trailing period.
    `DomainGuid` - Pointer to a GUID structure that specifies the GUID of the domain queried. If DomainGuid is not NULL and the domain specified by DomainName or ComputerName cannot be found, DsGetDcName attempts to locate a domain controller in the domain having the GUID specified by DomainGuid.
    `SiteName` - Pointer to a null-terminated string that specifies the name of the site where the returned domain controller should physically exist. If this parameter is NULL, DsGetDcName attempts to return a domain controller in the site closest to the site of the computer specified by ComputerName. This parameter should be NULL, by default.

    `DomainControllerInfo` - Pointer to a PDOMAIN_CONTROLLER_INFO value that receives a pointer to a DOMAIN_CONTROLLER_INFO structure that contains data about the domain controller selected. This structure is allocated by DsGetDcName. The caller must free the structure using the NetApiBufferFree function when it is no longer required.

This domain must have the TRUST_ATTRIBUTE_FOREST_TRANSITIVE trust attribute. If this parameter is NULL, the forest trust data for the domain hosted by ServerName is retrieved.
    `Flags` - Contains a set of flags that modify the behavior of this function. DS_GFTI_UPDATE_TDO: If this flag is set, DsGetForestTrustInformationW will update the forest trust data of the trusted domain identified by the TrustedDomainName parameter.
    `ForestTrustInfo` - Pointer to an LSA_FOREST_TRUST_INFORMATION structure pointer that receives the forest trust data that describes the namespaces claimed by the domain specified by TrustedDomainName. The Time member of all returned records will be zero.
  Returns:
    Returns NO_ERROR if successful or a Win32 error code otherwise.

### DsEnumerateDomainTrusts

    int DsEnumerateDomainTrusts(String serverName,
