Mon Sep 21 02:22:12 1998 Tim Janik <timj@gtk.org>
* NEWS file update for upcoming release of GLib + GModule
version 1.1.3, binary age 0, interface age 0. (GModule uses
the same version numbers as GLib.)
* glib.h: swap the inclusion of of float.h and limits.h to work
around a egcs 1.1 oddity on Solaris 2.5.1 (fix provided by
Per Abrahamsen <abraham@dina.kvl.dk>).
* glib.h:
* gscanner.c: renamed the GValue union to GTokenValue, this should
not affect source compatibility in most cases.
* ghash.c: added some g_return_if_fail() statements. make
g_hash_table_lookup_node() an inline function so we save an extra
function invokation on lookups.
Mon Sep 21 01:54:48 1998 Tim Janik <timj@gtk.org>
* gmodule.h:
* gmodule.c: renamed old _de_init functionality to _unload.
modules are now expected to export:
G_MODULE_EXPORT const gchar* g_module_check_init (GModule *module);
and
G_MODULE_EXPORT void g_module_unload (GModule *module);
returning a string other than NULL from g_module_check_init() will
prevent the module from being loaded. a call to g_module_make_resident()
from g_module_unload() will prevent the module from being unloaded and
still make it resident.
