| lzGetParmSigThe lzGetParmSig function returns a string indicating the number and types of parameters being passed to a linked external operator function. char* lzGetParmSig(| | LZObjectHandle hExOpUID | | // a handle to the external operator |
Parameters| hExOpUID | | | An Elzed object handle to the external operator. |
Return Value| | A string containing zero or more characters indicating the parameters being passed to the linked external operator.
The returned string will have as many characters as there are passed parameters. An empty string indicates that no parameters are being passed.
Parameter types are indicated with the following characters:
|
Character
|
Parameter Type
|
|
'B'
|
Boolean
|
|
'N'
|
Number
|
|
'S'
|
String
|
For example, an external operator being passed a numeric first parameter and a boolean second parameter would have a parameter signature of "NB". |
Remarks| | See lzGetParmSigB for Visual Basic support.
For linked external operators which accept varying numbers of parameters and/or varying types of parameters, the parameter signature can be used to quickly determine the nature of the call being made. In effect, it can be used to support a kind of operator overloading. |
