FIDO_INIT(3) FreeBSD 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.
