CURLOPT_PREQUOTE - commands to run before an FTP transfer
#include <curl/curl.h> CURLcode curl_easy_setopt(CURL *handle, CURLOPT_PREQUOTE, struct curl_slist *cmds);
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.
