将vswscanf从c转换为c ++？

Question

我需要将vswscanf函数从c转换为c ++ 使用宽字符串流和var arg， 你能救我吗？

my @codesign_args;
if (-e '$destApp/ResourceRules.plist') {  # If ResourceRules.plist exists, include it in codesign arguments, for backwards compatability
    @codesign_args = ("/usr/bin/codesign", "--force", "--preserve-metadata=identifier,entitlements,resource-rules",
                     "--sign", $opt{sign},
                     "--resource-rules=$destApp/ResourceRules.plist");
} else { # If ResourceRules.plist isn't found, don't include it in the codesign arguments
    @codesign_args = ("/usr/bin/codesign", "--force", "--preserve-metadata=identifier,entitlements",
                     "--sign", $opt{sign});
}
