File Content Extraction 25.3
Filter SDK C Programming Guide

# KVFilterInitOptions

This structure defines configuration options for a Filter session that you initialize by calling fpInit(). This structure is defined in `kvfiltersettings.h`.

    typedef struct tag_KVFilterInitOptions
    {
        KVStructHeader;

        KVCharSet outputCharSet;
        DWORD dwFlags;
    } KVFilterInitOptions;

## Member Descriptions

`KVStructHeader` | The version of the structure. See KVStructHead. You must use the macro `KVStructInit` to initialize the `KVStructHead` structure.
`outputCharSet` | The output character set to use when the source character set can be determined from the document or is specified by fpSetSrcCharSet(). The character sets are enumerated in `KVCharSet` in `kvcharset.h`. DEPRECATED: Output character encodings other than UTF-8 and UTF-16 are deprecated in File Content Extraction version 24.4. OpenText recommends that you use UTF-8 or UTF-16, which is output in Little Endian byte order. Support for other character encodings is currently available but might be removed in a future release.
`dwFlags` | Instructions on how to process a file or stream. See the following table for more information.

## Flags for dwFlags

`KVF_CONTENTACCESS` | Reserved for internal use.
`KVF_OUTOFPROCESS` | Enables out-of-process filtering. This is enabled by default. See Run Filter In Process.
`KVF_INPROCESS` | Enables in-process filtering. See Run Filter In Process.
`KVF_HEADERFOOTERTAGS` | Puts tags around header and footer data.
`KVF_HEADERFOOTER` | Extract headers and footers. DEPRECATED: This option is deprecated in File Content Extraction version 25.2 and later. Use the `KVFLT_HEADERFOOTER` option in fpSetConfig() instead. This option might be removed in future.
`KVF_UNICODEMSBLSB` | Uses the byte order for Big Endian systems (MSBLSB) for Unicode text. MSBLSB is the "Most Significant Byte Least Significant Byte." DEPRECATED: This option is deprecated in File Content Extraction version 24.4 and later. File Content Extraction now supports outputting text to only UTF-8 and UTF-16, in Little Endian format. This option might be removed in future.
`KVF_UNICODELSBMSB` | Uses the byte order for Little Endian systems (LSBMSB) for Unicode text. LSBMSB is the "Least Significant Byte Most Significant Byte." DEPRECATED: This option is deprecated in File Content Extraction version 24.4 and later. File Content Extraction now supports outputting text to only UTF-8 and UTF-16, in Little Endian format. This option might be removed in future.
`KVF_UNICODEMARKER` | Generates the byte order marker for Unicode text.
`KVF_NODEFAULTCHARSETCONVERT` | Prevents default conversion of document character encoding. See Disable Character Encoding Conversion.
`KVF_OOPLOGON` | Enables the out-of-process error log. See Enable or Disable Legacy Out-of-Process Error Logging. DEPRECATED: This option is deprecated in KeyView Filter version 24.1. Use fpSetConfig() to enable logging instead.
`KVF_OOPLOGOFF` | Disables the out-of-process error log. See Enable or Disable Legacy Out-of-Process Error Logging. DEPRECATED: This option is deprecated in KeyView Filter version 24.1. Use fpSetConfig() to disable logging instead.
`KVF_DETECT_OUTOFPROCESS` `KVF_DETECT_INPROCESS` | These flags specify whether file format detection occurs in-process or out-of-process. These flags override the `default_detect_inprocess` parameter in `formats.ini`. If you set neither of these flags, file detection behavior is determined by the `KVF_OUTOFPROCESS` or `KVF_INPROCESS` flags. If you do not set those flags, behavior is determined by `default_detect_inprocess` in `formats.ini`. See Run Filter In Process.
