Create a new keymap
SLKeyMap_List_Type *SLang_create_keymap (name, km)
char *name;
SLKeyMap_List_Type *km;
SLang_create_keymap creates a new keymap called name by
copying the key definitions from the keymap km. If km
is NULL, the newly created keymap will be empty and it is up
to the calling routine to initialize it via the
SLang_define_key and SLkm_define_keysym functions.
SLang_create_keymap returns a pointer to the new keymap, or
NULL upon failure.
