Thanks for your reply Werner. What you say makes sense to me, but I couldn't make anything of your source code - I'm very much a novice when it comes to C. I suspect I actually need to use a Fuse call to set up my mount. There is a lot of abstruse Fuse documentation to wade through, and I think I'll settle for just using the "system" C function, which works fine for me.

The mount system call can only mount file systems supported by the kernerl. There is no davfs kernel file system.
davfs2 uses the fuse file system which is designed to connect to all kinds of file systems that are running in userspace.

Please see the davfs2 sources, kernel_interface.c and mount_davfs.c, for how davfs2 is mounted.

Hello

I am trying to mount a davfs filesystem from within a C program with:

mount ("http://<uri>", "/mnt", "davfs", 0, NULL);

This command returns -1, and the mount fails.

The equivalent 'system' command works fine:

system ("mount -t davfs http://<uri> /mnt");

Have you any idea how I can go about investigating what went wrong with 'mount'?
