[libvirt] [PATCH 1/4] vz: make output arguments in prlsdkGetDomainIds as optional

prlsdkGetDomainIds() returns name and uuid for specified instance. Now output arguments can be NULL. It allows to get only necessary info(name or uuid). --- src/vz/vz_sdk.c | 34 +++++++++++++++++++--------------- 1 file changed, 19 insertions(+), 15 deletions(-) diff --git a/src/vz/vz_sdk.c b/src/vz/vz_sdk.c index 7973d6a..8181149 100644 --- a/src/vz/vz_sdk.c +++ b/src/vz/vz_sdk.c @@ -346,25 +346,29 @@ prlsdkGetDomainIds(PRL_HANDLE sdkdom, PRL_UINT32 len; PRL_RESULT pret; - len = 0; - /* get name length */ - pret = PrlVmCfg_GetName(sdkdom, NULL, &len); - prlsdkCheckRetGoto(pret, error); + if (name) { + len = 0; + /* get name length */ + pret = PrlVmCfg_GetName(sdkdom, NULL, &len); + prlsdkCheckRetGoto(pret, error); - if (VIR_ALLOC_N(*name, len) < 0) - goto error; + if (VIR_ALLOC_N(*name, len) < 0) + goto error; - PrlVmCfg_GetName(sdkdom, *name, &len); - prlsdkCheckRetGoto(pret, error); + PrlVmCfg_GetName(sdkdom, *name, &len); + prlsdkCheckRetGoto(pret, error); + } - len = sizeof(uuidstr); - PrlVmCfg_GetUuid(sdkdom, uuidstr, &len); - prlsdkCheckRetGoto(pret, error); + if (uuid) { + len = sizeof(uuidstr); + PrlVmCfg_GetUuid(sdkdom, uuidstr, &len); + prlsdkCheckRetGoto(pret, error); - if (prlsdkUUIDParse(uuidstr, uuid) < 0) { - virReportError(VIR_ERR_INTERNAL_ERROR, "%s", - _("Domain UUID is malformed or empty")); - goto error; + if (prlsdkUUIDParse(uuidstr, uuid) < 0) { + virReportError(VIR_ERR_INTERNAL_ERROR, "%s", + _("Domain UUID is malformed or empty")); + goto error; + } } return 0; -- 1.8.3.1
