-/* Read a hunk of data from FD, up until a terminator. The terminator
- is whatever the TERMINATOR function determines it to be; for

-
- In case of error, NULL is returned. In case of EOF and no data

+/* Read a hunk of data from FD, up until a terminator. The hunk is
+ limited by whatever the TERMINATOR callback chooses as its
+ terminator. For example, if terminator stops at newline, the hunk
+ will consist of a line of data; if terminator stops at two
+ newlines, it can be used to read the head of an HTTP response.
+ Upon determining the boundary, the function returns the data (up to
+ the terminator) in malloc-allocated storage.
+
+ In case of read error, NULL is returned. In case of EOF and no
+ data read, NULL is returned and errno set to 0. In case of having
+ read some data, but encountering EOF before seeing the terminator,
+ the data that has been read is returned, but it will (obviously)
+ not contain the terminator.
+
+ The TERMINATOR function is called with three arguments: the
+ beginning of the data read so far, the beginning of the current
+ block of peeked-at data, and the length of the current block.
+ Depending on its needs, the function is free to choose whether to
+ analyze all data or just the newly arrived data. If TERMINATOR
+ returns NULL, it means that the terminator has not been seen.
+ Otherwise it should return a pointer to the charactre immediately
+ following the terminator.
The idea is to be able to read a line of input, or otherwise a hunk
of text, such as the head of an HTTP request, without crossing the
boundary, so that the next call to fd_read etc. reads the data
after the hunk. To achieve that, this function does the following:
- 1. Peek at available data.
+ 1. Peek at incoming data.
2. Determine whether the peeked data, along with the previously
read data, includes the terminator.
