From de8e70596896cc9f85498a9981196ebc4465172e Mon Sep 17 00:00:00 2001 From: Vladimir Mezentsev Date: Thu, 16 Mar 2023 17:19:23 -0700 Subject: [PATCH] gprofng: Use prototype to call libc functions libcollector may not link against libC. We use dlsym() to get a function from libc. In some files, pointers to these functions do not have prototypes. I also moved the shared definitions to libcollector/collect.h. gprofng/ChangeLog 2023-03-15 Vladimir Mezentsev libcollector/collector.c: Add prototypes. libcollector/dispatcher.c: Likewise. libcollector/heaptrace.c: Likewise. libcollector/iotrace.c: Likewise. libcollector/linetrace.c: Likewise. libcollector/mmaptrace.c: Likewise. libcollector/synctrace.c: Likewise. libcollector/collector.h: Add CALL_REAL(), NULL_PTR(), and DBG_LT. --- gprofng/libcollector/collector.c | 13 +--- gprofng/libcollector/collector.h | 13 ++++ gprofng/libcollector/dispatcher.c | 67 ++++++++-------- gprofng/libcollector/heaptrace.c | 19 +---- gprofng/libcollector/iotrace.c | 17 ---- gprofng/libcollector/linetrace.c | 125 +++++++++++++++++------------- gprofng/libcollector/mmaptrace.c | 10 --- gprofng/libcollector/synctrace.c | 60 +++++++------- 8 files changed, 150 insertions(+), 174 deletions(-) diff --git a/gprofng/libcollector/collector.c b/gprofng/libcollector/collector.c index 55c52548b4e..df493658df9 100644 --- a/gprofng/libcollector/collector.c +++ b/gprofng/libcollector/collector.c @@ -37,12 +37,6 @@ #include "cc_libcollector.h" #include "tsd.h" -/* TprintfT(,...) definitions.
