nbdkit_is_tls - Man Page

get TLS status of the connection for nbdkit

Synopsis

 #include <nbdkit-plugin.h>

 int nbdkit_is_tls (void);

Description

nbdkit_is_tls returns true if and only if TLS negotiation has been completed on the current connection.  An nbdkit(1) plugin may use nbdkit_is_tls to limit connections according to whether the client connection is protected by TLS.  This function uses thread-local magic so no parameter is required

nbdkit-tls-fallback-filter(1) and the nbdkit --tls=require option are other alternatives.

Return Value

The function returns 1 (true) if TLS negotiation has been completed, or 0 (false) if not.

If there is an error it calls nbdkit_error(3) and returns -1.
