think of it as a (MAC address database), each mac address is delimited by a (.), my problem is after i search the file for total number of lines , iam unable to return the pointer to the initial position of the file in here i useseekg() and tellg()to manipulate the pointer to ...
It conflicts because you redefine the prototype for the original libc function getline() whose prototype is definied in <stdio.h>. From man 3 getline we have: ssize_t getline(char **lineptr, size_t *n, FILE *stream); If you redefine it with int getline(char line[], int maxline) yo...

But, I think it is because getline(theMatrix, theElement) function is returning 0 in 63rd line. For better understanding, the whole code is below. #include <iostream> #include <fstream> #include <sstream> #include <string> #include #include <set> #include <mkl.h> ...
