[libvirt] [PATCH 02/12] conf: use VIR_(INSERT_DELETE)_ELEMENTS in virNetworkUpdate backend

The already-written backend functions for virNetworkUpdate that add and delete items into lists within the a network were already debugged to work properly, but future such functions will use VIR_(INSERT|DELETE)_ELEMENTS_N instead, so these are changed for uniformity. --- src/conf/network_conf.c | 94 +++++++++++++++---------------------------------- src/conf/network_conf.h | 10 +++--- 2 files changed, 33 insertions(+), 71 deletions(-) diff --git a/src/conf/network_conf.c b/src/conf/network_conf.c index 8ad72e7..a8c42a0 100644 --- a/src/conf/network_conf.c +++ b/src/conf/network_conf.c @@ -2453,27 +2453,15 @@ virNetworkDefUpdateIPDHCPHost(virNetworkDefPtr def, goto cleanup; } } + /* add to beginning/end of list */ - if (VIR_REALLOC_N(ipdef->hosts, ipdef->nhosts +1) < 0) { + if (VIR_INSERT_ELEMENTS_N(ipdef->hosts, + command == VIR_NETWORK_UPDATE_COMMAND_ADD_FIRST + ?
