+# NAME
+
+curl_easy_ssls_import - import 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.

+
+# EXAMPLE
+
+~~~c
+int main(void)
+{
+  CURLSHcode sh;
+  CURLSH *share = curl_share_init();
+  CURLcode rc;
+  CURL *curl;
+
+  sh = curl_share_setopt(share, CURLSHOPT_SHARE, CURL_LOCK_DATA_SSL_SESSION);
+  if(sh)
+    printf("Error: %s\n", curl_share_strerror(sh));
+
+  curl = curl_easy_init();
+  if(curl) {
+    extern unsigned char *shmac, *sdata;
+    size_t hlen = 4, slen = 5;
+
+    curl_easy_setopt(curl, CURLOPT_SHARE, share);
+
+    /* read shmac and sdata from storage */
+    rc = curl_easy_ssls_import(curl, NULL, shmac, hlen, sdata, slen);
+
+    /* always cleanup */
+    curl_easy_cleanup(curl);
+  }
+  curl_share_cleanup(share);
+}
+~~~
+
+# %AVAILABILITY%
+
+# 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.
