PRELIMINARY SYNOPSIS int tls_available() DESCRIPTION If the global TLS initialisation could not been set up, tls_is_available() returns 0, otherwise 1. It is not very useful calling any other tls_*-efun if this one returns 0, since there is no TLS-encryption available. Most likely the global initialisation fails due to missing or unreadable key resp. certificate-file. HISTORY Introduced in LDMud 3.3.474 and following, backported to 3.2.11.
