How can I make fgets stop reading when it reaches a new line? Right now it will read the new line and continue until the buffer is full.
I was thinking something like this.
Code:while(fp!='\n'){ fgets(password, 256, fp); }

You should not be comparing a FILE pointer with '\n'. It should be:
since fgets returns a null pointer when end of file (with nothing read) or an error is detected.Code:while (fgets(password, 256, fp)) { /* ... */ }

A single call to "fgets()" does stop reading when it reaches a newline (unless the maximum specified number of characters has been read first, or EOF is encountered) - see here. Note that the newline is stored as part of the string, assuming there is room.How can I make fgets stop reading when it reaches a new line?
So you can check the string for the presence of the newline to see if the entire line has been read.
