>"Regarding g_malloc(), g_free() and siblings, these
functions are much safer than their libc equivalents. For
example, g_free() just returns if called with NULL. Also, if
USE_DMALLOC is defined, the definition for these functions
changes (in glib.h) to use MALLOC(), FREE() etc... If
MEM_PROFILE or MEM_CHECK are defined, there are even small
statistics made counting the used block sizes (shown by
g_mem_profile() / g_mem_check())."</SPAN
></P
><P
><SPAN
CLASS="QUOTE"
>"Considering the fact that glib provides an interface for
memory chunks to save space if you have lots of blocks that
are always the same size and to mark them ALLOC_ONLY if
needed, it is just straight forward to create a small saver
(debug able) wrapper around the normal malloc/free stuff as
well - just like gdk covers Xlib. ;)"</SPAN

><SPAN
CLASS="QUOTE"
>"Using g_error() and g_warning() inside of applications
like the GIMP that fully rely on gtk even gives the
opportunity to pop up a window showing the messages inside of
a gtk window with your own handler (by using
g_set_error_handler()) along the lines of
