TLS_ACCEPT_SOCKET(3)       Library Functions Manual       TLS_ACCEPT_SOCKET(3)

NAME
     tls_accept_socket, tls_accept_fds, tls_accept_cbs - accept an incoming
     client connection in a TLS server

SYNOPSIS
     #include <tls.h>

     int
     tls_accept_socket(struct tls *tls, struct tls **cctx, int socket);

     int
     tls_accept_fds(struct tls *tls, struct tls **cctx, int fd_read,
         int fd_write);

     int
     tls_accept_cbs(struct tls *tls, struct tls **cctx,
         ssize_t
         (*tls_read_cb)(struct tls *ctx, void *buf, size_t buflen,
         void *cb_arg),
         ssize_t (*tls_write_cb)(struct tls *ctx, const void
         *buf, size_t buflen, void *cb_arg), void *cb_arg);

DESCRIPTION
     After creating a TLS server context tls with tls_server(3) and
     configuring it with tls_configure(3), a server can accept a new client
     connection by calling tls_accept_socket() on an already established
     socket connection.

     Alternatively, a new client connection can be accepted over a pair of
     existing file descriptors by calling tls_accept_fds().

     Calling tls_accept_cbs() allows read and write callback functions to
     handle data transfers.  The specified cb_arg parameter is passed back to
     the functions, and can contain a pointer to any caller-specified data.

     All these functions create a new context suitable for reading and writing
     and return it in *cctx.

RETURN VALUES
     These functions return 0 on success or -1 on error.
