We can see from lib/stdio-impl.h and related files that there are essentially the following groups of stdio implementations: - glibc - FreeBSD, NetBSD, OpenBSD, Mac OS X, Cygwin, Android - AIX, HP-UX, Solaris, OpenServer, UnixWare, native Windows fopencookie exists on glibc, FreeBSD, Cygwin funopen exists on FreeBSD, NetBSD, OpenBSD, Mac OS X, Cygwin, Android What do you do on AIX, HP-UX, Solaris, OpenServer, UnixWare, native Windows ? Their stdio implementation does not contain function pointers in structs. Bruno
