ssh: Add support for libssh2 read timeout
Hook the new (1.11.0 or newer) libssh2 support for setting a read timeout
into the SERVER_RESPONSE_TIMEOUT option.  With this done, clients can use
the standard curl response timeout setting to also control the time that
libssh2 will wait for packets from a slow server.  This is necessary to
enable use of very slow SFTP servers.

.TH CURLOPT_SERVER_RESPONSE_TIMEOUT 3 "19 Jun 2014" libcurl libcurl
.SH NAME
CURLOPT_SERVER_RESPONSE_TIMEOUT \- time allowed to wait for server response
.SH SYNOPSIS
.nf
#include <curl/curl.h>
CURLcode curl_easy_setopt(CURL *handle, CURLOPT_SERVER_RESPONSE_TIMEOUT,
long timeout);
.fi
.SH DESCRIPTION
Pass a long. Causes libcurl to set a \fItimeout\fP period (in seconds) on the
amount of time that the server is allowed to take in order to send a response
message for a command before the session is considered dead. While libcurl is
waiting for a response, this value overrides \fICURLOPT_TIMEOUT(3)\fP. It is
recommended that if used in conjunction with \fICURLOPT_TIMEOUT(3)\fP, you set
\fICURLOPT_SERVER_RESPONSE_TIMEOUT(3)\fP to a value smaller than
\fICURLOPT_TIMEOUT(3)\fP.
This option was formerly known as \fBCURLOPT_FTP_RESPONSE_TIMEOUT\fP.
.SH DEFAULT
None
.SH PROTOCOLS
FTP, IMAP, POP3, SMTP, and SSH
.SH EXAMPLE
.nf
CURL *curl = curl_easy_init();
if(curl) {
curl_easy_setopt(curl, CURLOPT_URL, "ftp://example.com/slow.txt");
/* wait no more than 23 seconds */
curl_easy_setopt(curl, CURLOPT_SERVER_RESPONSE_TIMEOUT, 23L);
ret = curl_easy_perform(curl);
curl_easy_cleanup(curl);
}
.fi
.SH AVAILABILITY
Added in 7.10.8. Used under this name since 7.20.0
Support for SSH is predicated on a new enough (1.11.0) version of libssh2
being available when compiling libcurl.
.SH RETURN VALUE
Returns CURLE_OK if supported, and CURLE_UNKNOWN_OPTION if not. Returns
CURLE_BAD_FUNCTION_ARGUMENT if set to a negative value or a value that when
converted to milliseconds is too large.
