 API 

lzCheckExpB

The lzCheckExpB function converts the passed-in expression into enhanced postfix, and then reverts it back to infix.

BSTR lzCheckExpB(
   const char* szExpression   // string containing the expression
);

Parameters

szExpression
   A character string containing the infix expression to be checked.

Return Value

   Returns a BSTR containing an infix expression derived from the internally created enhanced postfix expression. You are responsible for disposing of the BSTR.

Remarks

   This call does 2 conversions. First, it converts the passed infix expression to enhanced postfix. If that conversion succeeds, the expression is reverted back to infix and returned. You can compare the returned infix expression to the original to check for parsing errors.

The call is intended to support Visual Basic. In VB, the lzCheckExp API call is mapped to this function.
