How to set the pointer back to the beginning of the file while parsing a csv file with the strtok()

Question

I have a .csv file that I want to parse as a database with rows and column numbers The solution I found uses strtok() (which might be not the perfect solution but I am happy to hear other suggestions). To my understanding strtok() progressively moves the pointer within the file. If you want to parse the file again, for example to access another cell, I have to close and reopen the file to set the pointer back to the beginning of the file. Is it possible to set the pointer at the beginning of the file (without having to close and reopen it)?
