.TH CURLOPT_DIRLISTONLY 3 "17 Jun 2014" "libcurl 7.37.0" "curl_easy_setopt options"
.SH NAME
CURLOPT_DIRLISTONLY \- ask for names only in a directory listing
.SH SYNOPSIS
#include <curl/curl.h>
CURLcode curl_easy_setopt(CURL *handle, CURLOPT_DIRLISTONLY, long listonly);
.SH 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 behaviour
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
doesn't end with a slash, which otherwise is necessary.
Do NOT use this option if you also use \fICURLOPT_WILDCARDMATCH(3)\fP as it
will effectively break that feature then.
.SH DEFAULT
0, disabled
