# nextpart*() - functions for reading files incrementally
#
# These functions aim to facilitate looking for (or waiting for)
# messages which may be logged more than once throughout the lifetime of
# a given named instance by outputting just the part of the file which
# has been appended since the last time we read it.
#
# Calling some of these functions causes temporary *.prev files to be
# created that need to be cleaned up manually (usually by a given system
# test's clean.sh script).
#
# Note that unlike other nextpart*() functions, nextpartread() is not
# meant to be directly used in system tests; its sole purpose is to
# reduce code duplication below.
#
# A quick usage example:
#
#     $ echo line1 > named.log
#     $ echo line2 >> named.log
#     $ nextpart named.log
#     line1
#     line2
#     $ echo line3 >> named.log
#     $ nextpart named.log
#     line3
#     $ nextpart named.log
#     $ echo line4 >> named.log
#     $ nextpartpeek named.log
#     line4
#     $ nextpartpeek named.log
#     line4
#     $ nextpartreset named.log
#     $ nextpartpeek named.log
#     line1
#     line2
#     line3
#     line4
#     $ nextpart named.log
#     line1
