From 985cba0c5c137a29e3fad8c400794ae71cb828a4 Mon Sep 17 00:00:00 2001 From: Stephen Hemminger Date: Tue, 9 Dec 2014 08:35:46 -0800 Subject: [PATCH] log: remove unnecessary stubs The read/seek/close stub functions are unnecessary on the log stream. Per glibc fopencookie man page: cookie_read_function_t *read If *read is a null pointer, then reads from the custom stream always return end of file. cookie_seek_function_t *seek If *seek is a null pointer, then it is not possible to perform seek operations on the stream. cookie_close_function_t *close If *close is NULL, then no special action is performed when the stream is closed.
