getvfsbyname
GETVFSBYNAME(3) BSD Library Functions Manual GETVFSBYNAME(3)
NAME
getvfsbyname -- get information about a file system
LIBRARY
Standard C Library (libc, -lc)
SYNOPSIS
#include <sys/param.h>
#include <sys/mount.h>
int
getvfsbyname(const char *name, struct xvfsconf *vfc);
DESCRIPTION
The getvfsbyname() function provides access to information about a file system module that is configured in the kernel. If successful, the
requested file system xvfsconf is returned in the location pointed to by vfc. The fields in a ``struct xvfsconf'' are defined as follows:
vfc_name the name of the file system
vfc_typenum the file system type number assigned by the kernel
vfc_refcount the number of active mount points using the file system
vfc_flags flag bits, as described below
The flags are defined as follows:
VFCF_STATIC statically compiled into kernel
VFCF_NETWORK may get data over the network
VFCF_READONLY writes are not implemented
VFCF_SYNTHETIC data does not represent real files
VFCF_LOOPBACK aliases some other mounted FS
VFCF_UNICODE stores file names as Unicode
VFCF_JAIL can be mounted from within a jail if security.jail.mount_allowed sysctl is set to 1
VFCF_DELEGADMIN supports delegated administration if vfs.usermount sysctl is set to 1
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 argument points to an invalid address.
[ENOENT] The name argument specifies a file system that is unknown or not configured in the kernel.
SEE ALSO
jail(2), mount(2), sysctl(3), jail(8), mount(8), sysctl(8)
