[libvirt] [PATCH 16/38] virlog: Introduce virLogOutputListFree

It is safe to pass -1 as the number of elements in the list as well as passing NULL as list reference. --- src/libvirt_private.syms | 1 + src/util/virlog.c | 20 ++++++++++++++++++++ src/util/virlog.h | 1 + 3 files changed, 22 insertions(+) diff --git a/src/libvirt_private.syms b/src/libvirt_private.syms index 433cf60..e594eaa 100644 --- a/src/libvirt_private.syms +++ b/src/libvirt_private.syms @@ -1752,6 +1752,7 @@ virLogGetOutputs; virLogLock; virLogMessage; virLogOutputFree; +virLogOutputListFree; virLogOutputNew; virLogParseDefaultPriority; virLogParseFilters; diff --git a/src/util/virlog.c b/src/util/virlog.c index e36ff73..5da1af7 100644 --- a/src/util/virlog.c +++ b/src/util/virlog.c @@ -1600,3 +1600,23 @@ virLogDefineFilters(virLogFilterPtr *filters, size_t nfilters) return virLogNbFilters; } + +/** + * virLogOutputsFreeList: + * @list: list of outputs to be freed + * @count: number of elements in the list + * + * Frees a list of outputs. + */ +void +virLogOutputListFree(virLogOutputPtr *list, int count) +{ + size_t i; + + if (!list || count < 0) + return; + + for (i = 0; i < count; i++) + virLogOutputFree(list[i]); + VIR_FREE(list); +} diff --git a/src/util/virlog.h b/src/util/virlog.h index 7573984..4f0eea7 100644 --- a/src/util/virlog.h +++ b/src/util/virlog.h @@ -196,6 +196,7 @@ extern int virLogOutputNew(virLogOutputFunc f, const char *name, unsigned int flags); extern void virLogOutputFree(virLogOutputPtr output); +extern void virLogOutputListFree(virLogOutputPtr *list, int count); /* * Internal logging API -- 2.4.3
