NAME

       gnutls_transport_set_pull_function - API function

SYNOPSIS

       #include <gnutls/gnutls.h>

       void    gnutls_transport_set_pull_function(gnutls_session_t    session,   gnutls_pull_func
       pull_func);

ARGUMENTS

       gnutls_session_t session
                   is a gnutls_session_t type.

       gnutls_pull_func pull_func
                   a callback function similar to read()

DESCRIPTION

       This is the function where you set a function for gnutls to receive  data.   Normally,  if
       you use berkeley style sockets, do not need to use this function since the default recv(2)
       will probably be ok.  The callback should return 0 on connection termination,  a  positive
       number indicating the number of bytes received, and -1 on error.

        gnutls_pull_func  is  of  the  form,  ssize_t (*gnutls_pull_func)(gnutls_transport_ptr_t,
       void*, size_t);
