       NAME
             sysfs - get file system type information

       SYNOPSIS
             #include <sys/fstyp.h>
             #include <sys/fsid.h>
             int sysfs(int opcode, const char *fsname);
             int sysfs(int opcode, int fs_index, char *buf);
             int sysfs(int opcode);

       DESCRIPTION
             sysfs returns information about the file system types
             configured in the system.  The number of arguments accepted by
             sysfs varies and depends on the opcode.  The currently
             recognized opcodes and their functions are:

             GETFSIND      Translate fsname, a null-terminated file-system
                           type identifier, into a file-system type index.

             GETFSTYP      Translate fs_index, a file-system type index,
                           into a null-terminated file-system type
                           identifier and write it into the buffer pointed
                           to by buf; this buffer must be at least of size
                           FSTYPSZ as defined in sys/fstyp.h.

             GETNFSTYP     Return the total number of file system types
                           configured in the system.

          Return Values
             On success, sysfs returns the file-system type index if the
             opcode is GETFSIND, 0 if the opcode is GETFSTYP, or the number
             of file system types configured if the opcode is GETNFSTYP.

             On failure, sysfs returns -1 and sets errno to identify the
             error.

          Errors
             In the following conditions, sysfs fails and sets errno to:

             EINVAL        fsname points to an invalid file-system
                           identifier; fs_index is zero, or invalid; opcode
                           is invalid.

             EFAULT        buf or fsname points to an invalid user address.
