CURLOPT_DIRLISTONLY(3) Library Functions Manual 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.
For FILE, this option has no effect yet as directories are always
listed in this mode.
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

curl_easy_setopt(curl, CURLOPT_DIRLISTONLY, 1L);
