/**
 * initializeStringBuffer - Initializes a character buffer of a specified size.
 *
 * @buffer_size: The size of the character buffer to allocate.
 *
 * Description:
 *   This function allocates a memory block for a character buffer of the given
 *   size and initializes it with all elements set to
 *  '\0'. It returns a pointer
 *   to the allocated memory.
 *
 *   If the provided buffer_size is less than or equal to 0, the function
 *   returns NULL and displays an error message.
 *
 *   The caller is responsible for freeing the allocated memory when it is no
 *   longer needed.
 *
 * Return: A pointer to the initialized character buffer, or NULL on failure.
