[GRASS5] question on D library/functions

[Andreas Lange]

Hi,

while trying to understand more of the internals of the libraries i
found that the D library and its functions (Dnew, Dclearscreen, Dchoose,
Derase, Dscreen, Dremove, Dcell) are not mentioned in the programmer's
manual. Can someone enlighten me? Are these functions only shortcuts to
the D_ and R_ library calls? Is there any reason that some modules use
system("d.erase") while others use Derase() and even others use
D_clear_window() ? What about system() and G_system(), should the
modules use always use G_system?

Thanks,

Andreas
