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 .
