Token Get File Descriptor


int globus_gss_assist_token_get_fd (void *arg, void **bufp, size_t *sizep)
 

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 *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)
