Updates unit number in expression

bool RenumExpression(
        TCHAR           *in_calc,
        TCHAR           *out_calc,
        RenumInfo               *ptrRenumInfo,
        int             MaxLength
)

Parameters

*in_calc	Expression before the update
*out_calc	Expression after the update (output)
*ptrRenumInfo	Flow editing information storage class
MaxLength	Maximum number of characters of the updated expression

Return Value

true: Successful completion

false: Unsuccessful completion

Description

Updates the reference unit number in the expression appropriately when flow editing is performed.

The storage area where the updated string is stored must be allocated by the calling side.

Specify the size of the allocated area to MaxLength.

This returns false without storing the updated expression if an error occurs, such as the cases that the length of the updated expression exceeds MaxLength or the required information data cannot be referenced.
