short GetProcVariables(long ProcID, VARIANT* Variables)
Description
This function returns an array that contains the names of the variables that are in the procedure's text. You should assign values to these variables by calling SetProcVariable() prior to running the procedure using RunProc().
Parameters
Name | Description |
---|---|
ProcID | The ID of the procedure, as returned from InitializeProc(). |
Variables |
A pointer to a VARIANT in which the result is stored. The result is an array of strings (variant type VT_ARRAY | VT_BSTR), with each string containing the name of one variable. If there are no variables in the procedure, the result is empty (variant type VT_EMPTY). You must initialize the VARIANT before calling this function. Visual Basic does this automatically. Visual C++ programmers should call VariantInit().

Return Value
The return value will be zero if successful or non-zero if unsuccessful. If there are no variables in the procedure, the return value is RS_ERROR_NO_DATA (-1). If the return value is non-zero, you can call GetLastErrorString() or GetLastErrorType() to get additional error information.
