SYNOPSIS

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
RETURN VALUES
The getvfsbyname() function returns the value 0 if successful; otherwise the value -1 is returned and the global variable errno is set to
indicate the error.
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 configured in the kernel.
