       int globus_gss_assist_token_send_fd_without_length (void *arg, void *buf, size_t size)

   Token Send File Descriptor Flag EX
       int globus_gss_assist_token_send_fd_ex (void *exp, void *buf, size_t size)

Detailed Description

       Token routines using fread and fwrite.

       Additional code has been added to detect tokens which are sent without a length field.
       These can currently be only SSL tokens. This does require some knowledge of the underlying
       GSSAPI, by the application, but is within the guidelines of the GSSAPI specifications.

       The get routine will automaticly attempt this test, while a new send routine will check a
       flag. The old send routine will work as before, sending a 4-byte length.

Function Documentation

   int globus_gss_assist_token_get_fd (void *arg, void **bufp, size_t *sizep)
       Use a open file discriptor to get a token. This function provides parameter types that
       allow it to be passed to globus_gss_assist_init_sec_context and
       globus_gss_assist_accept_sec_context

       Parameters:
           arg the FILE * stream cast to a void pointer
           bufp the resulting token
           sizep the size (number of bytes) read into bufp

       Returns:
           0 on success > 0 is internal return < 0 is the -errno

   int globus_gss_assist_token_send_fd (void *arg, void *buf, size_tsize)
       Write a token to the open file descriptor. WIll write it with a 4 byte length. This
       function provides parameter types that allow it to be passed to
       globus_gss_assist_init_sec_context and globus_gss_assist_accept_sec_context

       Parameters:
           arg the FILE * stream to send the token on
           buf the token
           size the size of the token in bytes

       Returns:
           0 on success >0 on error <0 on errno error

   int globus_gss_assist_token_send_fd_without_length (void *arg, void *buf, size_tsize)
       Write a token to the open file descripter. Will write it without a length. so as to

   int globus_gss_assist_token_send_fd_ex (void *exp, void *buf, size_tsize)
       Write a token to the open file descripter. will look at the flag to determine if the
       length field need to be written.

       Parameters:
           exp the globus_gss_assist_ex variable that holds the FILE * stream and flags to bet
           set
           buf the token buffer to send
           size size of the token buffer

       Returns:
           0 on success >0 on error <0 on errno error (-errno)
