fido_init,
fido_set_log_handler —
initialise the FIDO2 library
#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);
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.
