Developing Database Drivers for AOLserver -- Ns_PdFreeRowInfo

### Ns_PdFreeRowInfo

#### Overview

This function frees an Ns_PdRowInfo data structure.

#### Syntax

        void  Ns_PdFreeRowInfo(Ns_PdRowInfo * rowInfo, int fFreeData)

#### Description

If fFreeData is a non-zero value, then this function frees the data associated with the Ns_PdRowData structure (encapsulated in Ns_PdRowInfo) as well.

#### Psuedo-code Example

        /* Things italicized would be your DBMS-specific structures and
    calls. */
        /* defined in nspd.h */
        typedef struct Ns_PdRowData {
        int elSize;
        char *elData;
        } Ns_PdRowData;
        typedef struct Ns_PdRowInfo {
            int             numColumns;
            Ns_PdRowData   *rowData;
        };
        void
        DBMSFunction (void) {

            Ns_PdRowInfo   *getRowInfo, *bindRowInfo;
            if ((bindRowInfo = DBMSBindRow(state)) != NULL) {
               if ((getRowInfo =
    Ns_PdNewRowInfo(Ns_PdGetRowInfoNumColumns(bindRowInfo))) !=
    NULL) {
                    /* process getRowInfo */
                    /* ... */
                    /* free the getRowInfo structure when done */
                    Ns_PdFreeRowInfo(getRowInfo, 0);

               }
               /* free the bindRowInfo data and structure when done */
               Ns_PdFreeRowInfo(bindRowInfo, 1);
            }
        }
