// The sandbox is used to restrict sub-processes (renderer, plugin, 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 macOS the following requirements must be met:
// 1. Link the helper process executable with the cef_sandbox static library.
// 2. Call the cef_sandbox_initialize() function at the beginning of the
//    helper executable main() function and before loading the CEF framework
//    library. See include/wrapper/cef_library_loader.h for example usage.

///
// Initialize the sandbox for this process. Returns the sandbox context
// handle on success or NULL on failure. The returned handle should be
// passed to cef_sandbox_destroy() immediately before process termination.
