This switches the current hello_world to be hello_world-policy now, and hello_world is simplified to use the __default policy without any explicit policy of its own. Using the default policy means it relies on the system tls library to validate the tls connections using system trust arrangements, that won't work in cases where the configured tls library does not have its own trust store.

|
* Demonstrates the simplest example using the LWS high-level SS apis, doing
|
|
* an h2 GET from warmcat.com.
|
|
*
|
|
* It uses the default SS policy and relies on the tls library to know what
|
|
* CAs are trusted. See hello_world-policy for a version with its own defined
|
|
* policy which specifies the CA to trust.
|
|
*
|
|
* - main.c: (this file) boilerplate to create the lws_context
|
|
* and event loop
|
|
* - hello_world-ss.c: the secure stream user code
|
|
*
|
|
* Configure lws with -DCMAKE_BUILD_TYPE=DEBUG to build verbose logs, enable at
|
|
* runtime by giving -d 1039 or -d 1151 on this example commandline.
