FIDO_INIT(3)               Library Functions Manual               FIDO_INIT(3)

NAME
     fido_init, fido_set_log_handler - initialise the FIDO2 library

SYNOPSIS
     #include <fido.h>

     typedef void fido_log_handler_t(const char *);

     void
     fido_init(int flags);

     void
     fido_set_log_handler(fido_log_handler_t *handler);

DESCRIPTION
     The fido_init() function initialises the libfido2 library.  Its
     invocation must precede that of any other libfido2 function in the
     context of the executing thread.

     If FIDO_DEBUG is set in flags, then debug output will be emitted by
     libfido2 on stderr.  Alternatively, the FIDO_DEBUG environment variable
     may be set.

     If FIDO_DISABLE_U2F_FALLBACK is set in flags, then libfido2 will not
     fallback to U2F in fido_dev_open(3) if a device claims to support FIDO2
     but fails to respond to a CTAP 2.0 greeting.

     The fido_set_log_handler() function causes handler to be called for each
     log line generated in the context of the executing thread.  Lines passed
     to handler include a trailing newline character and are not printed by
     libfido2 on stderr.
