# fpInit()

This function initializes an Export session.

## Syntax

    KVErrorCode pascal _export fpInit(
        const char* pszKeyViewDir,
        const char* pszLicense,
        const char* pszIniFile,
        DWORD dWord,
        void** ppContext
    );

## Arguments

`pszKeyViewDir` | A pointer to a string that contains the path of the KeyView Export directory (where the readers and the `formats_e.ini` file are located). This is normally the `install\PLATFORM\bin` directory.
`pszLicense` | A pointer to a string that contains your license key, as provided by OpenText. Copy the key exactly, with no leading or trailing spaces.
`pszIniFile` | A pointer to a string that contains the full path of the KeyView Export configuration file, `formats_e.ini`. This file is normally stored in the directory `install\PLATFORM\bin`, where `install` is the path of the installation directory and `PLATFORM` is the name of the platform.
`dWord` | Reserved. Must be 0.
`ppContext` | A pointer to a context pointer for the session that you want to initialize. When you call `fpInit()`, the context pointer is set to the address of the new session context.

## Returns

The function returns an error code.

- When initialization is successful, the error code is `KVError_Success` and the session context is stored in `*ppContext`. Use the `*ppContext` context pointer in future calls to KeyView - it must be passed as the first argument to many of the File Extraction API and Export API functions.
- When initialization is unsuccessful, the return value is an error code (see KVErrorCode for more information), and `*ppContext` is set to `NULL`.

## Discussion

- If `pszKeyViewDir` is `NULL`, the required components cannot be found. Ensure that it is valid.

- To ensure multi-threaded conversions are thread-safe, you must create a unique context pointer for every thread by calling `fpInit()`. In addition, threads must not share context pointers, and the same context pointer must be used for all API calls in the same thread. Creating a context pointer for every thread does not affect performance because the context pointer uses minimal resources.

- When the conversion context is no longer required, terminate it by calling fpShutDown().

- On Windows, `pszKeyViewDir` and `pszIniFile` must be in the local Windows code page.

## Example

The following sample code is from the `cnv2html` sample program:

    error = (*KVHTMLInt.fpInit)(szDir, YOUR_KEYVIEW_LICENSE, NULL, 0, &pKVHTML);
    if (error != KVError_Success)
    {
        printf("Error initializing KVHTML: %d\n", error);
        mpFreeLibrary(hKVHTML);
        return 4;
    }
