GETVFSBYNAME(3)             BSD Programmer's Manual            GETVFSBYNAME(3)

NAME
     getvfsbyname - get information about a filesystem

SYNOPSIS
     #include <&lt;sys/types.h>&gt;
     #include <&lt;sys/mount.h>&gt;
     #include <&lt;kvm.h>&gt;

     int
     getvfsbyname(const char *name, struct vfsconf *vfc);

DESCRIPTION
     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

RETURN VALUES
     If the call to getvfsbyname is successful, 0 is returned.  Otherwise -1
     is returned and errno is set appropriately.

ERRORS
     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.

SEE ALSO
     sysctl(1),  mount(2),  sysctl(3),  mount(8)

HISTORY
     A variant of the getvfsbyname() function first appeared in FreeBSD 2.0.
