Check for underlying table conformance
SYNOPSIS
check_definition()
t1_keyinfo in First table key definition
t1_recinfo in First table record definition
t1_keys in Number of keys in first table
t1_recs in Number of records in first table
t2_keyinfo in Second table key definition
t2_recinfo in Second table record definition
t2_keys in Number of keys in second table
t2_recs in Number of records in second table
strict in Strict check switch
DESCRIPTION
This function compares two MyISAM definitions. By intention it was done
to compare merge table definition against underlying table definition.
It may also be used to compare dot-frm and MYI definitions of MyISAM
table as well to compare different MyISAM table definitions.
For merge table it is not required that number of keys in merge table
must exactly match number of keys in underlying table. When calling this
function for underlying table conformance check, 'strict' flag must be
set to false, and converted merge definition must be passed as t1_*.
Otherwise 'strict' flag must be set to 1 and it is not required to pass
converted dot-frm definition as t1_*.
RETURN VALUE
0 - Equal definitions.
1 - Different definitions.
