Subject: libwbclient: Abstract the DS_XXX flags for DsGetDcName().
X-Git-Tag: samba-4.0.0alpha6~801^2~1390
X-Git-Url: http://git.ipfire.org/gitweb.cgi?a=commitdiff_plain;h=34933a5c236ee489e4c11172820cdc0496b9e334;p=thirdparty%2Fsamba.git

libwbclient: Abstract the DS_XXX flags for DsGetDcName().

The wbcLookupDomainController() call supports a set of flags
defined in wbclient.h.  Add a mapping function between these
flags and the original DS_XXX flags in order to prevent having
to include the generated RPC headers in wbclient.h.
(This used to be commit 31614cd5e08dd6389c66e6ddf9f2d5429c6ab033)
