fstyp(3)                                                 fstyp(3)



     NAME
          fstyp - determine the file-system type

     SYNOPSIS
          #include <sys/fstypent.h>

          struct fstypent *fstype(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(Reg.)  are listed in /etc/fstypes.  See fstypes(4).


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

          able 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 con-

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

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


     RETURN VALUE

          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

          /etc/fstypes

          /etc/mtab

          /etc/fs/*/fstyp


     NOTES

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

          Berkeley Fast File Systems (UFS) as local systems.
