# fpInitWithLicenseData()

This function initializes an Export session with license information passed in function parameters rather than a license file. Its return value, `pContext`, is passed as the first parameter to the File Extraction interface and all other Export functions.

This function is similar to fpInit(), but it uses a different licensing method. You can use either fpInit() or `fpInitWithLicenseData` to initialize your Export session. However, these functions are mutually exclusive. That is, neither takes the context pointer from the other as an argument. If you call both functions, you initialize two distinct Export sessions, in the same way as calling fpInit() twice.

## Syntax

    void* pascal _export fpInitWithLicenseData(
        KVMemoryStream*    pMemAllocator,
        char*              pszKeyViewDir,
        const char* const  pszLicenseOrganization
        const char* const  pszLicenseKey
        char*              pszDataFile,
        KVErrorCode*       pError,
        DWORD              dWord);

## Arguments

`pMemAllocator` | This argument is deprecated in KeyView 12.10.0 and later, and should be `NULL`. If it is not, KeyView may use the functions in this developer-defined memory allocator to allocate memory.
`pszKeyViewDir` | A pointer to the directory where the Export components are located. This is normally the directory `install\OS\bin`, where `install` is the path name of the Export installation directory and `OS` is the name of the operating system.
`pszLicenseOrganization` | A pointer to a string that contains the organization name under which this installation of KeyView is licensed. This value is the company name that appears at the top of the license key provided by Micro Focus. Add the text exactly as it appears in this file.
`pszLicenseKey` | A pointer to a string that contains the license key for this installation of KeyView. This value is the appropriate license key provided by Micro Focus. The key is a string that contains 31 characters, for example `2TQD22D-2M6FV66-2KPF23S-2GEM5AB`. Type these characters exactly as they appear in the license key file, including the dashes, but do not include any leading or trailing spaces.
`pszDataFile` | A pointer to the directory and file name of the Export data file, `formats_e.ini`. This file determines whether a format is supported. If a format does not exist in this file, the conversion fails. The `formats_e.ini` file is normally stored in the directory `install\OS\bin`, where `install` is the path name of the Export installation directory and `OS` is the name of the operating system. See File Format Detection for more information.
`pError` | A pointer to an error code defined in `KVErrorCode` or `KVErrorCodeEx` in `kverrorcodes.h`. See KVErrorCode and KVErrorCodeEx.
`dWord` | Reserved. Must be 0.

## Returns

- If the call is successful, the return value is a pointer passed to all other functions.

- If the call is unsuccessful, the return value is a `NULL` pointer.

## Discussion

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

- If this function returns `NULL`, check `stderr` for the KeyView installation error messages, "`KeyView Export SDK License Key has Expired`" and "`KeyView Export SDK License Key is Invalid"`, and pass them to your application. See the Export SDK Installation Instructions for more information on the KeyView license feature.

- To ensure multithreaded conversions are thread-safe, you must create a unique context pointer for every thread by calling fpInit() or `fpInitWithLicenseData()`. 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, it should be terminated by calling fpShutDown().

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

## Example

The following sample code is from the `cnv2xml` sample program:

    pKVXML = (*KVXMLInt.fpInitWithLicenseData)(NULL, ".", YOUR_LICENSE_ORGANIZATION, YOUR_LICENSE_KEY, NULL, &error, 0);
    if(!pKVXML)
    {
        printf("Error initializing KVXML: %d\n", error);
        mpFreeLibrary(hKVXML);
        return 4;
    }
