gensio_get_type(3) Library Functions Manual gensio_get_type(3) NAME gensio_get_type, gensio_get_child, gensio_is_client, gensio_is_reliable, gensio_is_packet, gensio_is_authenticated, gensio_is_encrypted, gen- sio_is_message, gensio_is_mux - Return general information about a gensio SYNOPSIS #include <gensio/gensio.h> const char *gensio_get_type(struct gensio *io, unsigned int depth); struct gensio *gensio_get_child(struct gensio *io, unsigned int depth); bool gensio_is_client(struct gensio *io); bool gensio_is_reliable(struct gensio *io); bool gensio_is_packet(struct gensio *io); bool gensio_is_authenticated(struct gensio *io); bool gensio_is_encrypted(struct gensio *io); bool gensio_is_message(struct gensio *io); bool gensio_is_mux(struct gensio *io); DESCRIPTION gensio_get_type return the type string for the gensio (if depth is 0) or one of its children (depth > 0). Returns NULL if the depth is greater than the number of children. gensio_get_child returns the given child of the gensio, returns NULL if the depth is greater than the number of children. gensio_is_client returns true if the gensio a client or false if it is a server. gensio_is_reliable return true if the genio is reliable (won't loose data). Serial devices are not considered reliable, nor is UDP. Pretty much every- thing else is, because they won't drop data and are flow-controlled. gensio_is_packet returns if the genio is packet-oriented. In a packet-ori- ented genio, if one side writes a chunk of data, when the other side does a read it will get the same chunk of data as a single unit assuming it's buffer sizes are set properly. gensio_is_authenticated return true if the remote end authenticated, false if not. In the SSL case, this means that the remote certificate was re- ceived and verified (client and server, see gensio(5) SSL section for de- tails). For certauth server, this means that the authentication success- fully authenticated the certauth client by either certificate or password. gensio_is_encrypted returns true if the connection is encrypted, false if not. gensio_is_message returns if the genio is message-oriented. In a message- oriented genio, a write can explicitly mark message boundaries, these are delivered to the reader with those boundaries set. See gensio(5) for de- tails on how this works. gensio_is_mux return true if the genio is capable of multiplexing, meaning that it accepts an gensio_alloc_channel() call. Note that for the "gensio_is_xxx" type of requests, the properly is usually inherited from the child. So if you run a telnet gensio on top of an SSL gensio, the telnet gensio will return true for gensio_is_encrypted because SSL is encrypted.
