their default definitions. One possible use for overriding these is to
avoid the \f(CW\*(C`struct ev_loop *\*(C'\fR as first argument in all cases, or to use
method calls instead of plain function calls in \*(C+.

+.IX Subsection "EXPORTED API SYMBOLS"
+If you need to re-export the \s-1API\s0 (e.g. via a dll) and you need a list of
+exported symbols, you can use the provided \fISymbol.*\fR files which list
+all public symbols, one per line:
+.Sp
+.Vb 2
+\& Symbols.ev for libev proper
+\& Symbols.event for the libevent emulation
+.Ve
+.Sp
+This can also be used to rename all public symbols to avoid clashes with
+multiple versions of libev linked together (which is obviously bad in
+itself, but sometimes it is inconvinient to avoid this).
+.Sp
+A sed comamnd like this will create wrapper \f(CW\*(C`#define\*(C'\fR's that you need to
+include before including \fIev.h\fR:
+.Sp
+.Vb 1
+\& <Symbols.ev sed -e "s/.*/#define & myprefix_&/" >wrap.h
+.Ve
+.Sp
+This would create a file \fIwrap.h\fR which essentially looks like this:
+.Sp
+.Vb 4
+\& #define ev_backend myprefix_ev_backend
+\& #define ev_check_start myprefix_ev_check_start
+\& #define ev_check_stop myprefix_ev_check_stop
