Hi all,
I've written an application that uses getmntinfo which creates an
array of statfs structs and stores information about mounted
filesystems there.
The issue that I am having is detecting valid filesystems to do
further checks on. I am only interested in checking local filesystems
such as UFS.
Originally I was checking to see if f_type in the created struct was a
certain number. The man page described this as being
int f_type; /* type of filesystem */
I have now had to revert to checking f_fstypename against a string
(ufs only for now) because f_type seems to contain different numbers
for the same f_fstypename on different machines.
Eg on three different machines running FreeBSD 4.4-STABLE I got
1, 3 and 5 for f_type where the f_fstypename was ufs.
Is the f_type supposed to be consistent? If so, where is this normally
defined? If the f_type is not supposed to be consistent, is there any
way to check a the filesystem in the current statfs struct against a
list of values without having to do
if ( (strcmp(mounted_fs[count].f_fstypename, "ufs") != 0) ||
(strcmp(mounted_fs[count].f_fstypename, "hfs") !=0) )
?
Thanks
