# fpInit()

This function initializes an Export session. If initialization is successful, the `KVPDFContext` value pointed to by `pContext` is set to a valid context identifier. This context value must be passed as the first parameter to all other PDF Export functions.

## Syntax

    KVPDFState pascal fpInit(
        const char* const pszKeyViewDir,
        const char* const pszTempFolder,
        const char* const pszLicense,
        KVPDFContext* const pContext
    );

## Arguments

`pszKeyViewDir` | A null-terminated C string that contains the path of 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.
`pszTempFolder` | (Optional) A null-terminated C string that contains the path of a directory to use to store temporary files during the conversion process. Set this value to NULL to default to the system temporary 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.
`pContext` | A valid pointer to a value of type `KVPDFContext`. If initialization is successful, this target is set to a context-identifying value, which you must supply to subsequent export functions.

## Returns

- If the call is successful, a `KVPDFState` structure with `eErrorCode` set to `KVERR_Success`.

- If the call is unsuccessful, a `KVPDFState` structure that indicates the reason for the error.

## Discussion

- You can perform multiple calls to subsequent functions in serial using the same context (session).

- On Windows systems, specify the paths (`pszKeyViewDir` and `pszTempFolder`) in the local Windows code page.

- To ensure multithreaded 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 you must use the same context pointer for all API calls in the same thread.

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

- Internally, `KVPDFContext` is a pointer, and OpenText recommends that you initialize values of type `KVPDFContext` to NULL.

- If the call is unsuccessful, the value pointed to by `pContext` is not modified. No context has been created so there is no need to call `fpShutdown()`.

  IMPORTANT: It is not safe to call `fpShutdown()` with any value other than one arising from a successful call to `fpInit()` (or NULL).
