NAME
     fstypes - name-mapping information for file systems

SYNOPSIS
     #include <sys/fstypent.h>

DESCRIPTION
     /etc/fstypes contains information about file-system types.
     It can be modified by the system administrator using a text
     editor.  The file is used by commands that need to know the
     type of a specified file system.  It is also used by
     commands to determine the location of file-system-dependent
     utilities.

     The /etc/fstypes file consists of lines in the following
     format:
       numeric-type name-list [pathname-list]

     For example:

       0    5.2,svfs,s5    /etc/fs/5.2:/etc/fs/svfs


     The fields are separated by white space; a # as the first

     character indicates a comment.  A # after name-list or

     path-list indicates that the rest of the line is a comment.


     The placeholder numeric-type is the integer type that is

     passed to fsmount.  See fsmount(2).  These are defined in

     <sys/mount.h>. The name-list is a comma-separated list of

     character strings that describe the file-system type.  At

     least one of these is defined in <mntent.h>.  The

     pathname-list is a colon-separated list of pathnames.  These

     pathnames indicate where utility programs associated with

     the file-system type reside.  If this field is empty, the

     default location is /etc/fs/name-list.


     The entries in this file are accessed using fstypent, which

     reads the next entry from the file and returns a pointer to

     a struct fstypent. This structure is defined in

     <sys/fstypent> as:

       struct fstypent {
            int fstype;
            char **typelist;
            char *pathlist;
       };
