set_always_fatal
Description:
Sets the message levels which are always fatal, in any log domain.
When a message with any of these levels is logged the program terminates. You can only set the levels defined by GLib to be fatal. [ flags@GLib.LogLevelFlags.LEVEL_ERROR] is always fatal.
You can also make some message levels fatal at runtime by setting the `G_DEBUG` environment variable (see [Running GLib Applications]( glib-running.html)).
Libraries should not call this function, as it affects all messages logged by a process, including those from other libraries.
Structured log messages (using [func@GLib.log_structured] and [func@GLib.log_structured_array]) are fatal only if the default log writer is used; otherwise it is up to the writer function to determine which log messages are fatal. See [Using Structured Logging]( logging.html#using-structured-logging).
Parameters:
| fatal_mask |
the mask containing bits set for each level of error which is to be fatal |
Returns:
|
the old fatal mask |
