COPY(2) COPY(2)
Name
copy - Copies one box to another.
Synopsis
#include <ulib.h>
void copy(char* s, char* sc, char* d, char* dc)
Description
Copy copies the box with name s and constraint sc to the box
named d with constraint dc.
Both sc and dc must match as said in intro(1).
This system call is also used to "read" and "write" memory
from user memory. See vm(4) for a description of how to do
it.
Example
copy("/b/fs/a", nil, "/b/fs/b", nil);
copy("/b/fs/a", "%", "/b/fs/b", "%");
copy("/b/fs/a", "*!%", "/b/fs/b", "*!%");
copy("/b/fs/a", "*!wave", "/b/fs/b", "*!wave");
The first one copies /b/fs/a to /b/fs/b. The second does the
same but requests both boxes to be of the same architecture.
The third requests both boxes to be attached to the same
network. The last one requests both boxes to be attached to
the network named wave.
