# fpFreeImageInfos()

This function frees the memory associated with an image info context. Call this function when you have finished using the image info context for calls to `fpGetOutputImageCount()` and `fpGetOutputImageInfo()` (see fpGetOutputImageCount() and fpGetOutputImageInfo()).

## Syntax

    BOOL pascal fpFreeImageInfos (
          void* const pContext,
          void* const pImageInfos)

## Arguments

`pContext` | A pointer to a KeyView Export session that you initialized by calling fpInit(), and the pointer originally passed to fpGetOutputImageInfos() to create the image info context that you want to free.
`pImageInfos` | A pointer returned from `fpGetOutputImageInfos()`. See fpGetOutputImageInfos().

## Returns

- If the call is successful, the return value is `TRUE`.

- If the call is unsuccessful, the return value is `FALSE`.

## Discussion

- It is safe to call `fpFreeImageInfos()` with `pImageInfos()` set to `NULL`. The function returns `TRUE` in this case.
- You must call `fpFreeImageInfos()` before you call `fpShutdown()` (see fpShutDown()).
- You must not call `fpGetOutputImageCount()`, `fpGetOutputImageInfo()`, and `fpFreeImageInfos()` using an image info context pointer for which the associated system resources have already been successfully freed by using `fpFreeImageInfos()`.
