No, what he meant is: if you link to libraries 'foo' and 'bar', and library 'foo' also happens to use 'bar', then at runtime there will be only one copy of 'bar' in your process address space. If library 'bar' is not reentrant and has shared state, this shared state will affect functionality used by both your base program and library 'foo'. This is all within a single process. Multiple processes don't affect each other unless, as others have noted, you explicitly set up shared memory and the like. -- Peter Samuelson | org-tld!p12n!peter | http://p12n.org/ -- To UNSUBSCRIBE, email to [email protected] with a subject of "unsubscribe".
