Function svn_diff_get_binary_diff_original_stream 

pub unsafe extern "C" fn svn_diff_get_binary_diff_original_stream(
    bpatch: *const svn_diff_binary_patch_t,
    result_pool: *mut apr_pool_t,
) -> *mut svn_stream_t

Creates a stream allocated in @a result_pool from which the original (pre-patch-application) version of the binary patched file can be read.

@note Like many svn_diff_get functions over patches, this is implemented as reading from the backing patch file. Therefore it is recommended to read the whole stream before using other functions on the same patch file.
