Bear in mind that any code that deals with /proc or any other kernel  
filesystem is going to be limited to Linux systems. That may or may  
not be an issue. The rusage interface is somewhat more portable will  
provide at least some of what you're looking for.

Beyond rusage there isn't really an official portable interface for  
this type of data, but I would suggest that code for a portable SMNP  
agent would provide a good start as these agents aggregate the type of  
data you're looking for in order to make it available via the network  
for remote queries. Some will have libraries that hide the non- 
portability of the implementation. Or maybe SNMP is what you're  
looking for since it is already done and available?
