CURLOPT_PREQUOTE(3)        Library Functions Manual        CURLOPT_PREQUOTE(3)

NAME
       CURLOPT_PREQUOTE - commands to run before an FTP transfer

SYNOPSIS
       #include <curl/curl.h>

       CURLcode curl_easy_setopt(CURL *handle, CURLOPT_PREQUOTE,
                                 struct curl_slist *cmds);

DESCRIPTION
       Pass a pointer to a linked list of FTP commands to pass to the server
       after the transfer type is set. The linked list should be a fully valid
       list of struct curl_slist structs properly filled in as described for
       CURLOPT_QUOTE(3). Disable this operation again by setting a NULL to
       this option.

       These commands are not performed when a directory listing is performed,
       only for file transfers.

       While CURLOPT_QUOTE(3) and CURLOPT_POSTQUOTE(3) work for SFTP, this
       option does not.

DEFAULT
       NULL

PROTOCOLS
       FTP

EXAMPLE
       int main(void)
       {
         struct curl_slist *cmdlist = NULL;
         cmdlist = curl_slist_append(cmdlist, "SYST");

         CURL *curl = curl_easy_init();
         if(curl) {
           CURLcode res;
           curl_easy_setopt(curl, CURLOPT_URL, "ftp://example.com/foo.bin");

           /* pass in the FTP commands to run */
           curl_easy_setopt(curl, CURLOPT_PREQUOTE, cmdlist);

           res = curl_easy_perform(curl);

           curl_easy_cleanup(curl);
         }
       }

AVAILABILITY
       Along with the protocol support

RETURN VALUE
       Returns CURLE_OK if the option is supported, and CURLE_UNKNOWN_OPTION
       if not.
