CURLOPT_DIRLISTONLY(3) libcurl CURLOPT_DIRLISTONLY(3)
NAME
CURLOPT_DIRLISTONLY - ask for names only in a directory listing
SYNOPSIS
#include <curl/curl.h>
CURLcode curl_easy_setopt(CURL *handle, CURLOPT_DIRLISTONLY, long listonly);
DESCRIPTION
For FTP and SFTP based URLs a parameter set to 1 tells the library to
list the names of files in a directory, rather than performing a full
directory listing that would normally include file sizes, dates etc.
For POP3 a parameter of 1 tells the library to list the email message
or messages on the POP3 server. This can be used to change the default
behavior of libcurl, when combined with a URL that contains a message
ID, to perform a "scan listing" which can then be used to determine the
size of an email.
Note: For FTP this causes a NLST command to be sent to the FTP server.
Beware that some FTP servers list only files in their response to NLST;
they might not include subdirectories and symbolic links.
Setting this option to 1 also implies a directory listing even if the
URL does not end with a slash, which otherwise is necessary.
Do not use this option if you also use CURLOPT_WILDCARDMATCH(3) as it
effectively breaks that feature.
DEFAULT
0, disabled
PROTOCOLS
FTP, SFTP and POP3
EXAMPLE
CURL *curl = curl_easy_init();
if(curl) {
curl_easy_setopt(curl, CURLOPT_URL, "ftp://example.com/dir/");
/* list only */
curl_easy_setopt(curl, CURLOPT_DIRLISTONLY, 1L);
ret = curl_easy_perform(curl);
curl_easy_cleanup(curl);
}
AVAILABILITY
This option was known as CURLOPT_FTPLISTONLY up to 7.16.4. POP3 is sup-
ported since 7.21.5.
RETURN VALUE
Returns CURLE_OK if the option is supported, and CURLE_UNKNOWN_OPTION
if not.
