* \brief Replace string in string
*
* Replace \p from with \p to in \p *str, up to \p n times if \p n \> 0. If the
* function succeeds, \p *str will be passed to `free()` and \p *str will be
* updated to point to the newly allocated string. If \p n_replaced is not NULL,
* the number of replacements done will be stored at the value pointed by
* \p n_replaced. If the function fails, \p *str will be left unchanged.
*
* \param[in,out] str Pointer to string to modify
* \param[in] from String to replace
* \param[in] to Replacement string
* \param[in] n Number of replacements to attempt (0 to disable limit)
* \param[out] n_replaced Pointer to store number of replacements made
*
* \return Nothing if successful. Otherwise, the error code.
