+.Sh DESCRIPTION
+The
+.Fn fido_dev_info_manifest
+function fills
+.Fa devlist
+with up to
+.Fa ilen
+FIDO devices found by the underlying operating system.
+Currently only USB HID devices are supported.
+The number of discovered devices is returned in
+.Fa olen ,
+where
+.Fa olen
+is an addressable pointer.
+.Pp
+The
+.Fn fido_dev_info_new
+function returns a pointer to a newly allocated, empty device list
+with
+.Fa n
+available slots.
+If memory is not available, NULL is returned.
+.Pp
+The
+.Fn fido_dev_info_free
+function releases the memory backing
+.Fa *devlist_p ,
+where
+.Fa *devlist_p
+must have been previously allocated by
+.Fn fido_dev_info_new .
+The number
+.Fa n
+of allocated slots must also be provided.
+On return,
+.Fa *devlist_p
+is set to NULL.
+Either
+.Fa devlist_p
+or
+.Fa *devlist_p
+may be NULL, in which case
+.Fn fido_dev_info_free
+is a NOP.
+.Pp
+The
+.Fn fido_dev_info_ptr
+function returns a pointer to slot number
+.Fa i
+of
+.Fa devlist .
+It is the caller's responsibility to ensure that
+.Fa i
+is bounded.
+Please note that the first slot has index 0.
+.Pp
+The
+.Fn fido_dev_info_path
+returns the filesystem path or subsystem-specific identification
+string of
+.Fa di .
+.Pp
+The
+.Fn fido_dev_info_product
+function returns the product ID of
+.Fa di .
+.Pp
+The
+.Fn fido_dev_info_vendor
+function returns the vendor ID of
+.Fa di .
+.Pp
+The
+.Fn fido_dev_info_manufacturer_string
+function returns the manufacturer string of
+.Fa di .
+.Pp
+The
+.Fn fido_dev_info_product_string
+function returns the product string of
+.Fa di .
+.Pp
+An example of how to use the functions described in this document
+can be found in the
+.Pa examples/manifest.c
+file shipped with
+.Em libfido2 .
+.Sh RETURN VALUES
+The
+.Fn fido_dev_info_manifest
+function always returns
+.Dv FIDO_OK .
+If a discovery error occurs, the
+.Fa olen
+pointer is set to 0.
+.Pp
+The pointers returned by
+.Fn fido_dev_info_ptr ,
+.Fn fido_dev_info_path ,
+.Fn fido_dev_info_manufacturer_string ,
+and
+.Fn fido_dev_info_product_string
+are guaranteed to exist until
+.Fn fido_dev_info_free
+is called on the corresponding device list.
