CURLOPT_TIMEOUT_MS(3)					     curl_easy_setopt options					     CURLOPT_TIMEOUT_MS(3)

NAME

       CURLOPT_TIMEOUT_MS - set maximum time the request is allowed to take

SYNOPSIS

       #include <curl/curl.h>

       CURLcode curl_easy_setopt(CURL *handle, CURLOPT_TIMEOUT_MS, long timeout);

DESCRIPTION

       Pass  a long as parameter containing timeout - the maximum time in milliseconds that you allow the libcurl transfer operation to take. Nor-
       mally, name lookups can take a considerable time and limiting operations to less than a few minutes risk aborting perfectly  normal  opera-
       tions. This option may cause libcurl to use the SIGALRM signal to timeout system calls.

       If  libcurl is built to use the standard system name resolver, that portion of the transfer will still use full-second resolution for time-
       outs with a minimum timeout allowed of one second.

       In unix-like systems, this might cause signals to be used unless CURLOPT_NOSIGNAL(3) is set.

       If both CURLOPT_TIMEOUT(3) and CURLOPT_TIMEOUT_MS(3) are set, the value set last will be used.

       Since this puts a hard limit for how long time a request is allowed to take, it has limited use in dynamic use cases with varying  transfer
       times. You are then advised to explore CURLOPT_LOW_SPEED_LIMIT(3), CURLOPT_LOW_SPEED_TIME(3) or using CURLOPT_PROGRESSFUNCTION(3) to imple-
       ment your own timeout logic.

DEFAULT

       Default timeout is 0 (zero) which means it never times out during transfer.

PROTOCOLS

       All

EXAMPLE

       CURL *curl = curl_easy_init();
       if(curl) {
	 curl_easy_setopt(curl, CURLOPT_URL, "http://example.com");

	 /* complete within 20000 milliseconds */
	 curl_easy_setopt(curl, CURLOPT_TIMEOUT_MS, 20000L);

	 curl_easy_perform(curl);
       }

AVAILABILITY

       Always

RETURN VALUE

       Returns CURLE_OK

CURLOPT_REDIR_PROTOCOLS(3)				     curl_easy_setopt options					CURLOPT_REDIR_PROTOCOLS(3)

NAME

       CURLOPT_REDIR_PROTOCOLS - set protocols allowed to redirect to

SYNOPSIS

       #include <curl/curl.h>

       CURLcode curl_easy_setopt(CURL *handle, CURLOPT_REDIR_PROTOCOLS, long bitmask);

DESCRIPTION

       Pass  a long that holds a bitmask of CURLPROTO_* defines. If used, this bitmask limits what protocols libcurl may use in a transfer that it
       follows to in a redirect when CURLOPT_FOLLOWLOCATION(3) is enabled. This allows you to limit specific transfers to only be allowed to use a
       subset of protocols in redirections.

       Protocols denied by CURLOPT_PROTOCOLS(3) are not overridden by this option.

       By  default  libcurl  will allow all protocols on redirect except several disabled for security reasons: Since 7.19.4 FILE and SCP are dis-
       abled, and since 7.40.0 SMB and SMBS are also disabled. CURLPROTO_ALL enables all protocols on redirect, including those disabled for secu-
       rity.

       These are the available protocol defines:
       CURLPROTO_DICT
       CURLPROTO_FILE
       CURLPROTO_FTP
       CURLPROTO_FTPS
       CURLPROTO_GOPHER
       CURLPROTO_HTTP
       CURLPROTO_HTTPS
       CURLPROTO_IMAP
       CURLPROTO_IMAPS
       CURLPROTO_LDAP
       CURLPROTO_LDAPS
       CURLPROTO_POP3
       CURLPROTO_POP3S
       CURLPROTO_RTMP
       CURLPROTO_RTMPE
       CURLPROTO_RTMPS
       CURLPROTO_RTMPT
       CURLPROTO_RTMPTE
       CURLPROTO_RTMPTS
       CURLPROTO_RTSP
       CURLPROTO_SCP
       CURLPROTO_SFTP
       CURLPROTO_SMB
       CURLPROTO_SMBS
       CURLPROTO_SMTP
       CURLPROTO_SMTPS
       CURLPROTO_TELNET
       CURLPROTO_TFTP

DEFAULT

       All protocols except for FILE, SCP and since 7.40.0 SMB and SMBS.

PROTOCOLS

       All

EXAMPLE

       curl = curl_easy_init();
       if(curl) {
	 /* pass in the URL from an external source */
	 curl_easy_setopt(curl, CURLOPT_URL, argv[1]);

	 /* only allow redirects to HTTP and HTTPS URLs */
	 curl_easy_setopt(curl, CURLOPT_REDIR_PROTOCOLS,
			  CURLPROTO_HTTP | CURLPROTO_HTTPS);

	 /* Perform the request */
	 curl_easy_perform(curl);
       }

AVAILABILITY

       Added in 7.19.4, before then it would follow all protocols.

RETURN VALUE

       Returns CURLE_OK if the option is supported, and CURLE_UNKNOWN_OPTION if not.
