void import(char* nm, char* addr, char* sel, int p);
The box imported is located at the server whose network address is addr and is known by that server as the box with name and constraint given by sel.
The special network address any may be used to request that any box advertised as sel be imported to the name space as soon as the advertisement is received.
The p parameter determines the place where the entry is placed in the name space. This is important since entries are searched in order from the ones above to the ones below. For automatic imports of advertised boxes, entries are added to the place determined at the time of the call. Values for p can be:
MABOVE determines that the entry goes above existing ones.
MBELOW determines that it goes below existing ones.
MUNIX determines that goes above after removing existing ones for the same name.
