 `strbuf_getline`::

+       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
+       any) in the buffer.
+
+`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.
