From 6bf2e6f07c133f7b145a4726c5d962f14c650ca7 Mon Sep 17 00:00:00 2001 From: Eric Wong Date: Wed, 5 Mar 2014 14:45:44 +0100 Subject: libfuse: implement readdirplus for high-level API Reuse the old "readdir" callback, but add a flags argument, that has FUSE_READDIR_PLUS in case this is a "plus" version. Filesystems can safely ignore this flag, but if they want they can add optimizations based on it: i.e. only retrieve the full attributes in PLUS mode. The filler function is also given a flags argument and the filesystem can set FUSE_FILL_DIR_PLUS if all the attributes in "stat" are valid. --- example/fusexmp.c | 6 ++++-- 1 file changed, 4 insertions(+), 2 deletions(-) (limited to 'example/fusexmp.c') diff --git a/example/fusexmp.c b/example/fusexmp.c index 6f63ae9..fe20f57 100755 --- a/example/fusexmp.c +++ b/example/fusexmp.c @@ -81,13 +81,15 @@ static int xmp_readlink(const char *path, char *buf, size_t size) static int xmp_readdir(const char *path, void *buf, fuse_fill_dir_t filler, - off_t offset, struct fuse_file_info *fi) + off_t offset, struct fuse_file_info *fi, + enum fuse_readdir_flags flags) { DIR *dp; struct dirent *de; (void) offset; (void) fi; + (void) flags; dp = opendir(path); if (dp == NULL) @@ -98,7 +100,7 @@ static int xmp_readdir(const char *path, void *buf, fuse_fill_dir_t filler, memset(&st, 0, sizeof(st)); st.st_ino = de->d_ino; st.st_mode = de->d_type << 12; - if (filler(buf, de->d_name, &st, 0)) + if (filler(buf, de->d_name, &st, 0, 0)) break; } -- cgit v1.2.3
