GETVFSBYNAME(3) BSD Programmer's Manual GETVFSBYNAME(3)
getvfsbyname - get information about a filesystem
getvfsbyname(const char *name, struct vfsconf *vfc);
The getvfsbyname() function provides access to information about a
filesystem module that is configured in the kernel. If successful, the
requested filesystem vfsconf is returned in the location pointed to by
vfc. The fields in a ``struct vfsconf'' are defined as follows:
vfc_name the name of the filesystem
vfc_typenum the filesystem type number assigned by the kernel
vfc_refcount the number of active mount points using the filesystem
vfc_flags flag bits that are used to initialize a new mount point us-
ing the filesystem
If the call to getvfsbyname is successful, 0 is returned. Otherwise -1
is returned and errno is set appropriately.
The following errors may be reported:
[EFAULT] The vfc pointer contains an invalid address.
[ENOENT] The name specifies a filesystem that is unknown or not con-
figured in the kernel.
sysctl(1), mount(2), sysctl(3), mount(8)
A variant of the getvfsbyname() function first appeared in FreeBSD 2.0.
