// The sandbox is used to restrict sub-processes (renderer, GPU, etc) from
// directly accessing system resources. This helps to protect the user from
// untrusted and potentially malicious Web content. See
// http://www.chromium.org/developers/design-documents/sandbox for complete
// details.
//
// To enable the sandbox on Windows the following requirements must be met:
// 1. Use the same executable for the browser process and all sub-processes.
// 2. Link the executable with the cef_sandbox static library.
// 3. Call the cef_sandbox_info_create() function from within the executable
//    (not from a separate DLL) and pass the resulting pointer into both the
//    CefExecuteProcess() and CefInitialize() functions via the
//    |windows_sandbox_info| parameter.

///
// Create the sandbox information object for this process. It is safe to create
// multiple of this object and to destroy the object immediately after passing
// into the CefExecuteProcess() and/or CefInitialize() functions.
