Function svn_error_purge_tracing 

pub unsafe extern "C" fn svn_error_purge_tracing(
    err: *mut svn_error_t,
) -> *mut svn_error_t

Returns an error chain that is based on @a err’s error chain but does not include any error tracing placeholders. @a err is not modified, except for any allocations using its pool.

The returned error chain is allocated from @a err’s pool and shares its message and source filename character arrays. The returned error chain should not be cleared because it is not a fully fledged error chain, only clearing @a err should be done to clear the returned error chain. If @a err is cleared, then the returned error chain is unusable.

@a err can be #SVN_NO_ERROR. If @a err is not #SVN_NO_ERROR, then the last link in the error chain must be a non-tracing error, i.e, a real error.
