# KV_CONFIG_Arg

This structure defines configurable arguments to use as the data in the fpSetConfig() function when you set the `KVFLT_SetConfigurableArguments` flag to `TRUE`. The structure is described in `kvtypes.h`.

Use this structure to control the filtering of hidden data from Microsoft Excel documents. See Hidden Data in Microsoft Excel Documents.

    typedef struct _KV_CONFIG_ARG_TAG
    {
        unsigned int       keyID;
        int                keyType;
        KV_CONFIG_DATA     keyData;
        unsigned int       keyDataSize;
    }
    KV_CONFIG_Arg;

## Member Descriptions

`keyID` | Determines the kind of configuration flags that you can use as values of `keyData`. If you use the same `keyID` more than once, the most recent setting overrides the previous setting.
`keyType` | The type of data for the `keyData` element. Set to `KV_INT32ARG`.
`keyData` | `KV_CONFIG_DATA` is a union defined in `kvtypes.h`. Only `intArg` is supported, where the value of `intArg` is one of the flags in the corresponding `keyID`.
`keyDataSize` | The size of `keyData`. This is reserved for future use.
