Documented some of the quirks and limitations of the C/WASM crossover. Keep the JS code from calling into the C code after an exit() has been triggered.

+ Notes and Caveats + ( + hide) +

+

+

+ This JavaScript application runs a C application which has been + compiled into WASM (Web Assembly). As such, it has certain + limitations. Those include, but are not limited to: +

+

It cannot recover after a call to + exit(). If the native code triggers + an exit, reloading the page is the only way to restart + the application. (Making the app restartable without reloading + the page would require significant surgery in the C code.) +
It cannot perform any file I/O, and running + any command which attempts to do so might trigger an + exit(). +
A number of dot-commands available in the CLI shell are + explicitly removed from this version of the shell. +
