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.
