|function: map_empty||library: avlmap|
long map_empty( MAP mapping )
map_empty deletes all members of the specified mapping. This function works directly on the underlying tree structure to delete the members faster that calling map_delete one at a time on each member. The scaling formula for map_empty is O(n) where n is the number of members.
The errno value is set by system functions when an error occurs.
