Function pointers are often a nice way to implement state machines,
for instance http://dotat.at/cgi/git?p=unifdef.git;a=blob;f=unifdef.c


The byte code in a threaded code interpreter is often just a list of
function pointers.


There are a lot of function pointers in the unix kernel. Have a look
at Lions' commentary, Stevens' TCP/IP Illustrated volume 2, and
McKusick & Neville-Neil's Design and Implementation of the FreeBSD
operating system.
