// FUNCTION: LPVOID CheckAndReAllocBuffer(LPVOID, size_t, LPCSTR)

// PURPOSE: Checks and ReAllocates a buffer if necessary.
//
// PARAMETERS:
// lpBuffer - Pointer to buffer to be checked. Can be NULL.
// sizeBufferMinimum - Minimum size that lpBuffer should be.
// szApiPhrase - Phrase to print if an error occurs.
//
// RETURN VALUE:
// Returns a pointer to a valid buffer that is guarenteed to be
// at least sizeBufferMinimum size.
// Returns NULL if an error occured.
//
// COMMENTS:
//
// This function is a helper function intended to make all of the
// line API Wrapper Functions much simplier. It allocates (or
// reallocates) a buffer of the requested size.
//
// The returned pointer has been allocated with LocalAlloc,
// so LocalFree has to be called on it when you're finished with it,
// or there will be a memory leak.
//
// Similarly, if a pointer is passed in, it *must* have been allocated
// with LocalAlloc and it could potentially be LocalFree()d.
//
// If lpBuffer == NULL, then a new buffer is allocated. It is
// normal to pass in NULL for this parameter the first time and only
// pass in a pointer if the buffer needs to be reallocated.
//
// szApiPhrase is used only for debugging purposes.
//
// It is assumed that the buffer returned from this function will be used
// to contain a variable sized structure. Thus, the dwTotalSize field
// is always filled in before returning the pointer.
//
