# If SQLITE_DEFAULT_AUTOVACUUM is set to true, then a simulated IO error

# file when the file on disk is only 1 page. The pager layer detects that
# this has happened and suppresses the error returned by the OS layer.

# Usage: do_ioerr_test <test number> <options...>
#
# This proc is used to implement test cases that check that IO errors
# are correctly handled. The first argument, <test number>, is an integer 
# used to name the tests executed by this proc. Options are as follows:
#
#     -tclprep          TCL script to run to prepare test.
#     -sqlprep          SQL script to run to prepare test.
#     -tclbody          TCL script to run with IO error simulation.
#     -sqlbody          TCL script to run with IO error simulation.
#     -exclude          List of 'N' values not to test.
#     -start            Value of 'N' to begin with (default 1)
#
#     -cksum            Boolean. If true, test that the database does
#                       not change during the execution of the test case.
