     15 # NAME
     16 
     17 CURLOPT_PREQUOTE - commands to run before an FTP transfer
     18 
     19 # SYNOPSIS
     20 
     21 ~~~c
     22 #include <curl/curl.h>
     23 
     24 CURLcode curl_easy_setopt(CURL *handle, CURLOPT_PREQUOTE,
     25                           struct curl_slist *cmds);
     26 ~~~
     27 
     28 # DESCRIPTION
     29 
     30 Pass a pointer to a linked list of FTP commands to pass to the server after
     31 the transfer type is set. The linked list should be a fully valid list of
     32 struct curl_slist structs properly filled in as described for
     33 CURLOPT_QUOTE(3).
     34 
     35 Using this option multiple times makes the last set string override the
     36 previous ones. Set it to NULL to disable its use again.
     37 
     38 libcurl does not copy the list, it needs to be kept around until after the
     39 transfer has completed.
     40 
     41 While CURLOPT_QUOTE(3) and CURLOPT_POSTQUOTE(3) work for SFTP,
     42 this option does not.
     43 
     44 # DEFAULT
     45 
     46 NULL
     47 
     48 # %PROTOCOLS%

     50 # EXAMPLE
     51 
     52 ~~~c
     53 int main(void)
     54 {
     55   struct curl_slist *cmdlist = NULL;
     56   cmdlist = curl_slist_append(cmdlist, "SYST");
     57 
     58   CURL *curl = curl_easy_init();
     59   if(curl) {
     60     CURLcode res;
     61     curl_easy_setopt(curl, CURLOPT_URL, "ftp://example.com/foo.bin");
     62 
     63     /* pass in the FTP commands to run */
     64     curl_easy_setopt(curl, CURLOPT_PREQUOTE, cmdlist);
     65 
     66     res = curl_easy_perform(curl);
     67 
     68     curl_easy_cleanup(curl);
     69   }
     70   curl_slist_free_all(cmdlist);
     71 }
