|MAFW Reference Manual|
Users of MAFW can enable the display of log and informational messages
selectively in run-time. To do so you need to invoke
which takes a string describing what levels of messages to log; others
are all disabled. You can override this compile-time specification by
setting the $MAFW_LOG environment variable.
The specification string is like
"[domain]:level[,[domain]:level]*", where `domain' is the
log_domain argument of g_log, and `level' is either "ERROR",
"CRITICAL", "WARNING", "MESSAGE", "INFO", "DEBUG", "ALL", "PRINT"
or "-" (lettercase is not taken into account) telling the minimum
required urgency of messages to be logged (ie. don't log less
"-" means don't log anything from that domain. If `domain' is "default" `level' applies to all messages for which G_LOG_DOMAIN wasn't defined. Otherwise if the `domain' part is empty `level' will apply to domains not specifically mentioned in the string.
All possible values of `level' except "ALL" and "PRINT" makes
silent. If `level' is "ALL" the domain is effectively ignored by the
filtering mechanism (ie. it's processing is left as it was). "PRINT" is
like "-", but leaves
# silence everything MAFW_LOG=":-" ./app # silence 'foo' MAFW_LOG="foo:-" ./app # only mafw messages less important than message MAFW_LOG="mafw:warning" ./app # all from mafw-dbus MAFW_LOG="mafw-dbus:debug" ./app
void mafw_log_init (gchar const *doms);
Disables the display of all log messages except those matching
whose format is described in the section introduction. If
NULL, a sane default is used. If it's empty no changes will be made
This function works as expected only for the first time invoked and only if no log handlers were set before because there's no way clearing out log handlers in general.
