Function svn_config_get_server_setting_int 

pub unsafe extern "C" fn svn_config_get_server_setting_int(
    cfg: *mut svn_config_t,
    server_group: *const c_char,
    option_name: *const c_char,
    default_value: apr_int64_t,
    result_value: *mut apr_int64_t,
    pool: *mut apr_pool_t,
) -> *mut svn_error_t

Retrieve value into @a result_value corresponding to @a option_name for a given @a server_group in @a cfg, or return @a default_value if none is found.

The config will first be checked for a default, then will be checked for an override in a server group. If the value found is not a valid integer, a @c svn_error_t* will be returned.
