CURLOPT_PREQUOTE - Man Page

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.
