5 check-ins using file tls.c version 5e9f95c600

Added support for optional TLS commands BIO_CTRL_POP and BIO_CTRL_PUSH. BIO_CTRL_PUSH is an optional value that is not handled in the tlsBIO:BioCtrl(). The larger problem is that the library does not support new optional commands because it returns -2 for unknown cmds in BioCtrl(). I would suggest changing the default return value to 0. I confirmed that this fixed the issue. Source: https://core.tcl-lang.org/tcltls/tktview/006bd0c74e check-in: 602c39a56c user: bohagan tags: trunk, main
