[libvirt] [PATCH 10/38] virlog: Introduce virLogDefineOutputs

Prepare a method that only defines a set of outputs. It takes a list of outputs, preferably created by virLogParseOutputs. The original set of outputs is reset and replaced by the new user-provided set of outputs. --- src/libvirt_private.syms | 1 + src/util/virlog.c | 25 +++++++++++++++++++++++++ src/util/virlog.h | 1 + 3 files changed, 27 insertions(+) diff --git a/src/libvirt_private.syms b/src/libvirt_private.syms index 99b3b55..e97ec45 100644 --- a/src/libvirt_private.syms +++ b/src/libvirt_private.syms @@ -1743,6 +1743,7 @@ virLockSpaceReleaseResourcesForOwner; # util/virlog.h virLogDefineFilter; virLogDefineOutput; +virLogDefineOutputs; virLogGetDefaultPriority; virLogGetFilters; virLogGetNbFilters; diff --git a/src/util/virlog.c b/src/util/virlog.c index 9059722..e5923ce 100644 --- a/src/util/virlog.c +++ b/src/util/virlog.c @@ -1539,3 +1539,28 @@ virLogSetOutputs(const char *outputs) return ret; } + + +/** + * virLogDefineOutputs: + * @outputs: new set of outputs to be defined + * @noutputs: number of outputs in @outputs + * + * Resets any existing set of outputs and defines a completely new one. + * + * Returns number of outputs successfully defined or -1 in case of error; + */ +int +virLogDefineOutputs(virLogOutputPtr *outputs, size_t noutputs) +{ + if (virLogInitialize() < 0) + return -1; + + virLogLock(); + virLogResetOutputs(); + virLogOutputs = outputs; + virLogNbOutputs = noutputs; + virLogUnlock(); + + return virLogNbOutputs; +} diff --git a/src/util/virlog.h b/src/util/virlog.h index 4141ecd..166db5a 100644 --- a/src/util/virlog.h +++ b/src/util/virlog.h @@ -224,5 +224,6 @@ extern void virLogVMessage(virLogSourcePtr source, va_list vargs) ATTRIBUTE_FMT_PRINTF(7, 0); bool virLogProbablyLogMessage(const char *str); +int virLogDefineOutputs(virLogOutputPtr *outputs, size_t noutputs); #endif -- 2.4.3
