@deftypefun int lt_dlpreload_default (const lt_dlsymlist *@var{preloaded})
Set the default list of preloaded modules to @var{preloaded},
which won't be deleted by @code{lt_dlpreload}.
Note that this function does *not* require libltdl to be initialized
using @code{lt_dlinit} and can be used in the program to register
the default preloaded modules.
Usually the main function in the program will set libtool's default
symbol list:
@example
extern const lt_dlsymlist lt_preloaded_symbols[];
...
lt_dlpreload_default(lt_preloaded_symbols);
@end example
Libltdl defines the macros @code{LTDL_PRELOADED_SYMBOLS} and
@code{LTDL_SET_PRELOADED_SYMBOLS}, which hide these libtool dependent
declaration for you.
Set the default list of preloaded modules to @var{preloaded}, which
won't be deleted by @code{lt_dlpreload}. Note that this function does
@emph{not} require libltdl to be initialized using @code{lt_dlinit} and
can be used in the program to register the default preloaded modules.
Instead of calling this function directly, most programs will use the
macro @code{LTDL_SET_PRELOADED_SYMBOLS}.
Return 0 on success.

@defmac LTDL_SET_PRELOADED_SYMBOLS()
Set the default list of preloaded symbols.
