# NAME
|
|
|
|
curl_easy_ssls_export - export SSL sessions
|
|
|
|
# SYNOPSIS
|
|
|
|
~~~c
|
|
#include <curl/curl.h>
|
|
|
|
CURLcode curl_easy_ssls_import(CURL *handle,
|
|
const char *session_key,
|
|
const unsigned char *shmac, size_t shmac_len,
|
|
const unsigned char *sdata, size_t sdata_len);
|
|
~~~
|
|
|
|
# DESCRIPTION
|
|
|
|
This function imports a previously exported SSL session ticket. **sdata** and
|
|
**sdata_len** must always be provided. If **session_key** is **NULL**, then
|
|
**shmac** and **shmac_len** must be given as received during the export.
|
|
See curl_easy_ssls_export(3) for a description of those.
|
|
|
|
Import of session tickets from other curl versions may fail due to changes
|
|
in the handling of **shmac** or **sdata**. A session ticket which has
|
|
already expired is silently discarded.

# RETURN VALUE
|
|
|
|
This function returns a CURLcode indicating success or error.
|
|
|
|
CURLE_OK (0) means everything was OK, non-zero means an error occurred, see
|
|
libcurl-errors(3). If CURLOPT_ERRORBUFFER(3) was set with curl_easy_setopt(3)
|
|
there can be an error message stored in the error buffer when non-zero is
|
|
returned.
