SYNOPSIS (EXPERIMENTAL)

int

tls_available

(

)

DESCRIPTION

If the global TLS initialisation could not be set up, tls_is_available() returns 0, otherwise 1.

It is not very useful to call any other tls_* efun if this one returns 0, since there is no TLS-encryption available.

Most likely the global initialisation failed due to a missing or unreadable key resp. certificate-file.
