Example:

	Copy Code
AT_ERRCOUNT errCount = 0 ; LPAT_WCHAR patterns [] = { L"the" , L"bart" , L"the" } ; HIG_REC_APPROX_REGEX higRecApproxRegex = 0 ; IG_REC_approx_regex_create( &higRecApproxRegex ) ; errCount = IG_REC_approx_regex_pattern_set ( higRecApproxRegex, patterns, 2 ) ; IG_REC_approx_regex_delete( higRecApproxRegex ) ;

Copy Code

AT_ERRCOUNT errCount = 0 ;
LPAT_WCHAR patterns [] = { L"the" , L"bart" , L"the" } ;
HIG_REC_APPROX_REGEX higRecApproxRegex = 0 ;

IG_REC_approx_regex_create( &higRecApproxRegex ) ;
errCount = IG_REC_approx_regex_pattern_set
                           ( higRecApproxRegex,
                             patterns,
                             2 
                           ) ;
IG_REC_approx_regex_delete( higRecApproxRegex ) ;
