+ Read a line from a FILE *, overwriting the existing contents
+ of the strbuf. The second argument specifies the line
terminator character, typically `'\n'`.
+ Reading stops after the terminator or at EOF. The terminator
+ is removed from the buffer before returning. Returns 0 unless
+ there was nothing left before EOF, in which case it returns `EOF`.
+
+`strbuf_getwholeline`::
+
+ Like `strbuf_getline`, but keeps the trailing terminator (if

+
+`strbuf_getwholeline_fd`::
+
+ Like `strbuf_getwholeline`, but operates on a file descriptor.
+ It reads one character at a time, so it is very slow. Do not
+ use it unless you need the correct position in the file
+ descriptor.
