NAME

6       CURLOPT_DIRLISTONLY - ask for names only in a directory listing
7

SYNOPSIS

9       #include <curl/curl.h>
10
11       CURLcode curl_easy_setopt(CURL *handle, CURLOPT_DIRLISTONLY, long listonly);
12

DESCRIPTION

14       For  FTP  and SFTP based URLs a parameter set to 1 tells the library to
15       list the names of files in a directory, rather than performing  a  full
16       directory listing that would normally include file sizes, dates etc.
17
18       For  POP3  a parameter of 1 tells the library to list the email message
19       or messages on the POP3 server. This can be used to change the  default
20       behavior  of  libcurl, when combined with a URL that contains a message
21       ID, to perform a "scan listing" which can then be used to determine the
22       size of an email.
23
24       Note:  For FTP this causes a NLST command to be sent to the FTP server.
25       Beware that some FTP servers list only files in their response to NLST;
26       they might not include subdirectories and symbolic links.
27
28       Setting  this  option to 1 also implies a directory listing even if the
29       URL does not end with a slash, which otherwise is necessary.
30
31       Do NOT use this option if you also use CURLOPT_WILDCARDMATCH(3)  as  it
32       will effectively break that feature then.
