Feature #17611: Expose `rb_execarg` interfaces and `rb_grantpt`

• Status: Open

[nobu (Nobuyoshi Nakada)]

An opaque struct rb_execarg has been added 9 years ago, and the latest change on functions deal with it was 3 years ago.
Also, it has been 3 years since rb_grantpt was added.
These seem stable enough to expose now, but are still internal, and stopping pty from becoming a gem.

Maybe rb_grantpt can be more generic, e.g., calling a function with supspending waitpid, though.
