getpwent() uses a single passwd structure, when you make successive calls
to it, the pointer returned from the previous call points to the newly
updated passwd structure, this is why you are getting multiple copies of
the same structure. you will need to make a function to copy the fields of
the passwd structure.

this memory is leaked since you assign to user in the very next line

this memory is leaked as well
