This seems to be a glibc question. Folks on news:comp.os.linux.development.[apps|sys] might know better. Referencing internal data structures is inherently non-portable. You might look in /proc/<pid>/fd/ which seems to have file descriptor numbers represented as symbolic links to the file(s) opened. fflush (NULL); flushes all fopen'ed files, but that doesn't mean writes are actually committed (you need sync/fsync for that). > Any idea what they call it, > or how one can find all currently open FILEs? > > Perhaps there is a better way? > > A general guide to porting underlinux /debian would be appreciated.
