+.Sh DESCRIPTION
+The
+.Fn fido_dev_open
+function opens the device pointed to by
+.Fa path ,
+where
+.Fa dev
+is a freshly allocated or otherwise closed
+.Vt fido_dev_t .
+.Pp
+The
+.Fn fido_dev_close
+function closes the device represented by
+.Fa dev .
+If
+.Fa dev
+is already closed,
+.Fn fido_dev_close
+is a NOP.
+.Pp
+The
+.Fn fido_dev_cancel
+function cancels any pending requests on
+.Fa dev .
+.Pp
+The
+.Fn fido_dev_new
+function returns a pointer to a newly allocated, empty
+.Vt fido_dev_t .
+If memory cannot be allocated, NULL is returned.
+.Pp
+The
+.Fn fido_dev_free
+function releases the memory backing
+.Fa *dev_p ,
+where
+.Fa *dev_p
+must have been previously allocated by
+.Fn fido_dev_new .
+On return,
+.Fa *dev_p
+is set to NULL.
+Either
+.Fa dev_p
+or
+.Fa *dev_p
+may be NULL, in which case
+.Fn fido_dev_free
+is a NOP.
+.Pp
+The
+.Fn fido_dev_force_fido2
+function can be used to force CTAP2 communication with
+.Fa dev .
+.Pp
+The
+.Fn fido_dev_force_u2f
+function can be used to force CTAP1 (U2F) communication with
+.Fa dev .
+.Pp
+The
+.Fn fido_dev_is_fido2
+function returns
+.Dv true
+if
+.Fa dev
+is a FIDO 2 device.
+.Pp
+The
+.Fn fido_dev_protocol
+function returns the CTAPHID protocol version identifier of
+.Fa dev .
+.Pp
+The
+.Fn fido_dev_build
+function returns the CTAPHID build version number of
+.Fa dev .
+.Pp
+The
+.Fn fido_dev_flags
+function returns the CTAPHID capabilities flags of
+.Fa dev .
+.Pp
+The
+.Fn fido_dev_major
+function returns the CTAPHID major version number of
+.Fa dev .
+.Pp
+The
+.Fn fido_dev_minor
+function returns the CTAPHID minor version number of
+.Fa dev .
+.Pp
+For the format and meaning of the CTAPHID parameters returned by
+functions above, please refer to the FIDO Client to Authenticator
+Protocol (CTAP) specification.
+.Sh RETURN VALUES
+On success,
+.Fn fido_dev_open
+and
+.Fn fido_dev_close
+return
+.Dv FIDO_OK .
+On error, a different error code defined in
+.In fido/err.h
+is returned.
