Function svn_wc_get_pristine_copy_path 

pub unsafe extern "C" fn svn_wc_get_pristine_copy_path(
    path: *const c_char,
    pristine_path: *mut *const c_char,
    pool: *mut apr_pool_t,
) -> *mut svn_error_t

Set @a *pristine_path to the path of the “normal” pristine text file for the versioned file @a path.

If @a path does not have a pristine text, set @a *pristine_path to a path where nothing exists on disk (in a directory that does exist).

@note: Before version 1.7, the behaviour in that case was to provide the path where the pristine text would be if it were present. The new behaviour is intended to provide backward compatibility for callers that open or test the provided path immediately, and not for callers that store the path for later use.

@deprecated Provided for backwards compatibility with the 1.5 API. Callers should use svn_wc_get_pristine_contents() instead.
