Read line by line until EOF is reached. If the first character of the current line is a null character (or a newline character before its removal if you are using fgets()), then it is a blank line.

Loop through each character in the line then. isspace comes to mind.

Eh, but the first character of those lines in question would be a space, not a null or newline character.
