fstyp(3)                                                 fstyp(3)



NAME
     fstyp - determines the file-system type

SYNOPSIS
     #include <sys/fstypent.h>

     struct fstypent *fstyp(name)

     char *name;


DESCRIPTION

     fstyp determines the type of the file system associated with

     the file name.  The file-system types supported on A/UX are

     listed in /etc/fstypes (see fstypes(4)).


     If the file name is a block or character device and is

     readable by the calling process, fstyp attempts to determine

     the file-system type by executing (through exec(2)) the

     file-system-dependent versions of the fstyp(1) command.

     These commands read the file-sytem superblocks and perform

     consistency checks on the file-system data.  See fs(4).

     Otherwise, fstyp uses the information returned by statfs(2).


STATUS MESSAGES AND VALUES

     The return value is a pointer to a fstypent structure.  If

     the file-system type cannot be determined, a null pointer is

     returned.


FILES

     /etc/fstab

          File containing file system table

     /etc/fstypes

          File containing file system types

     /etc/mtab

          File containing the mount table

     /etc/fs/*/fstyp

          File containing a file system type


NOTES

     A/UX currently supports System V file systems (SVFS) and

     Berkeley Fast File Systems (UFS) as local systems.
