Token Send File Descriptor
int globus_gss_assist_token_send_fd (void *arg, void *buf, size_t size)
Token Send File Descriptor Without Length
int globus_gss_assist_token_send_fd_without_length (void *arg, void

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_t size)
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_t size)
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_t
size)
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)
