Unfortunately, I can't think of a way to support dynamic flag modification (other than perhaps adding a dbus method to do it). From 6b9569c22193a1d0c8d8d6f38692d5f8f43429c9 Mon Sep 17 00:00:00 2001 From: Andres Salomon <dilinger(a)collabora.co.uk&gt; Date: Sat, 8 Aug 2009 20:06:12 -0400 Subject: [PATCH] ofono: add zoned debug support This adds debug flags so that when users are debugging, they can pass arguments to --debug to specify what they want shown. --debug without any args defaults to prior behavior. --- include/log.h | 11 +++++++++-- src/log.c | 11 +++++++---- src/main.c | 25 +++++++++++++++++++++++-- src/ofono.h | 2 +- 4 files changed, 40 insertions(+), 9 deletions(-) diff --git a/include/log.h b/include/log.h index 47e5ec8..8a82f13 100644 --- a/include/log.h +++ b/include/log.h @@ -26,6 +26,10 @@ extern "C" { #endif +typedef enum { + OFONO_DEBUG_CORE = 1 << 0, +} ofono_debug_flags; + /** * SECTION:log * @title: Logging premitives @@ -36,8 +40,11 @@ extern void ofono_info(const char *format, ...) __attribute__((format(printf, 1, 2))); extern void ofono_error(const char *format, ...) __attribute__((format(printf, 1, 2))); -extern void ofono_debug(const char *format, ...) - __attribute__((format(printf, 1, 2))); +extern void __ofono_debug(ofono_debug_flags flag, const char *format, ...) + __attribute__((format(printf, 2, 3))); +#define ofono_debug(format, ...) \ + __ofono_debug(OFONO_DEBUG_CORE, (format), ##__VA_ARGS__) + /** * DBG: diff --git a/src/log.c b/src/log.c index 273e3ba..167fe21 100644 --- a/src/log.c +++ b/src/log.c @@ -29,6 +29,7 @@ #include "ofono.h" static volatile gboolean debug_enabled = FALSE; +static guint debug_flags; /** * ofono_info: @@ -67,7 +68,8 @@ void ofono_error(const char *format, ...) } /** - * ofono_debug: + * __ofono_debug: + * @flag: zone flag (ie, OFONO_DEBUG_CORE) * @format: format string * @varargs: list of arguments * @@ -76,11 +78,11 @@ void ofono_error(const char *format, ...) * The actual output of the debug message is controlled via a command line * switch.
