To clear the file consistency flags field in the
superblock of the file specified in the command line.
Description:
With the implementation of file locking, the library uses the
file consistency flags field in the superblock to mark a
file as in writing or SWMR writing mode when a file is opened.
The library will clear this field when the file closes.
However, a situation may occur where an open file is closed
without going through the normal library file closing procedure,
and this field will not be cleared as a result. An example would
be if an application program crashed. This situation will prevent
a user from opening the file. The h5clear tool will
clear the file consistency flags field, and the user can
then open the file.
