NAME

       curl_easy_send - sends raw data over an "easy" connection

SYNOPSIS

       #include <curl/easy.h>

       CURLcode curl_easy_send( CURL *curl, const void *buffer,  size_t buflen, size_t *n);

DESCRIPTION

       This function sends arbitrary data over the established connection. You may use it together with curl_easy_recv(3) to implement custom pro-
       tocols using libcurl. This functionality can be particularly useful if you use proxies and/or SSL encryption: libcurl  will  take  care	of
       proxy negotiation and connection set-up.

       buffer is a pointer to the data of length buflen that you want sent.  The variable n points to will receive the number of sent bytes.

       To establish the connection, set CURLOPT_CONNECT_ONLY option before calling curl_easy_perform(3). Note that curl_easy_send(3) will not work
       on connections that were created without this option.

       You must ensure that the socket is writable before calling curl_easy_send(3), otherwise the call will return CURLE_AGAIN -  the	socket	is
       used  in  non-blocking  mode  internally. Use curl_easy_getinfo(3) with CURLINFO_LASTSOCKET to obtain the socket; use your operating system
       facilities like select(2) to check if it can be written to.

AVAILABILITY

       Added in 7.18.2.

RETURN VALUE

       On success, returns CURLE_OK and stores the number of bytes actually sent into *n. Note that this may very well be less than the amount you
       wanted to send.

       On failure, returns the appropriate error code.

       If there's no socket available to use from the previous transfer, this function returns CURLE_UNSUPPORTED_PROTOCOL.

EXAMPLE

       See sendrecv.c in docs/examples directory for usage example.

NAME

       curl_easy_recv - receives raw data on an "easy" connection

SYNOPSIS

       #include <curl/easy.h>

       CURLcode curl_easy_recv( CURL *curl, void *buffer, size_t buflen, size_t *n);

DESCRIPTION

       This  function receives raw data from the established connection. You may use it together with curl_easy_send(3) to implement custom proto-
       cols using libcurl. This functionality can be particularly useful if you use proxies and/or SSL encryption: libcurl will take care of proxy
       negotiation and connection set-up.

       buffer  is  a  pointer to your buffer that will get the received data. buflen is the maximum amount of data you can get in that buffer. The
       variable n points to will receive the number of received bytes.

       To establish the connection, set CURLOPT_CONNECT_ONLY option before calling curl_easy_perform(3). Note that curl_easy_recv(3) does not work
       on connections that were created without this option.

       You  must ensure that the socket has data to read before calling curl_easy_recv(3), otherwise the call will return CURLE_AGAIN - the socket
       is used in non-blocking mode internally. Use curl_easy_getinfo(3) with CURLINFO_LASTSOCKET to obtain the socket; use your operating  system
       facilities like select(2) to check if it has any data you can read.

AVAILABILITY

       Added in 7.18.2.

RETURN VALUE

       On success, returns CURLE_OK, stores the received data into buffer, and the number of bytes it actually read into *n.

       On failure, returns the appropriate error code.

       If  there  is  no data to read, the function returns CURLE_AGAIN. Use your operating system facilities to wait until the data is ready, and
       retry.

EXAMPLE

       See sendrecv.c in docs/examples directory for usage example.
