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.
+A parameter set to 1 tells the library to just list the names of files in a
+directory, instead of doing a full directory listing that would include file
+sizes, dates etc. This works for FTP and SFTP URLs.
-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.
+This causes an FTP NLST command to be sent on an 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.
