Per the first suggestion posted, I am now going to try to eliminate the part of the code that stores the entire input file in a vector of string.
This is the code that opens the input file and parses it into rows.
The rest of the code directs a row of code into a stringstream, and then it is parsed into "cells" using a tab delimiter.
I could direct the string newSplitsLine into the string stream in the while loop, and continue with the rest as is, or I cold change the code to parse the string instead of the stringstream. I suppose I could also parse the ifstream from the input file directly into cells, but that would be more involved.
Is this what was meant by, "A function that loads from a stream, which your file-opening member could use too, instead of just one member which loads from a filename and nothing else." in the first reply post? If I just parse splitsInput, the stream from the input file, I would have to parse by tab for the cells, and then the end of line character to differentiate between rows. Can that be done on a stream with getline, or do I have to divert each row into some temp structure and then parse the temp structure into cells?
I am trying to lighten the code and remove redundant steps. Let me know if anyone wants me to post the whole src.

we have 2.2.0 of opends running on RedHat 2.6.21 and we're trying to setup a structure that will suit our needs.

Is it possible to view all the functions exported by a given object file?
"dump -tv" comes the closest, but what exactly am I looking for to determine whether the symbol exists in the object file?
Essentially, I have a library that requires a call to "xdr_sizeof" and the compile is failing... (5 Replies)
