- .TH curl_easy_cleanup 3 "22 Aug 2007" "libcurl 7.17.0" "libcurl Manual"
- .SH NAME
- curl_easy_cleanup - End a libcurl easy handle
- .SH SYNOPSIS
- .B #include <curl/curl.h>
- .BI "void curl_easy_cleanup(CURL *" handle ");"
- .SH DESCRIPTION
- This function must be the last function to call for an easy session. It is the
- opposite of the \fIcurl_easy_init(3)\fP function and must be called with the
- same \fIhandle\fP as input that a \fIcurl_easy_init(3)\fP call returned.
- This might close all connections this handle has used and possibly has kept
- open until now - unless it was attached to a multi handle while doing the
- transfers. Don't call this function if you intend to transfer more files,
- re-using handles is a key to good performance with libcurl.
- Occasionally you may get your progress callback or header callback called from
- within \fIcurl_easy_cleanup(3)\fP (if previously set for the handle using
- \fIcurl_easy_setopt(3)\fP). Like if libcurl decides to shut down the
- connection and the protocol is of a kind that requires a command/response
- sequence before disconnect. Examples of such protocols are FTP, POP3 and IMAP.
- Any use of the \fBhandle\fP after this function has been called and have
- returned, is illegal. \fIcurl_easy_cleanup(3)\fP kills the handle and all
- memory associated with it!
- Passing in a NULL pointer in \fIhandle\fP will make this function return
- immediately with no action.
- .SH "OLD TIMES"
- For libcurl versions before 7.17,: after you've called this function, you can
- safely remove all the strings you've previously told libcurl to use, as it
- won't use them anymore now.
- .SH RETURN VALUE
- None
- .SH EXAMPLE
- .nf
- CURL *curl = curl_easy_init();
- if(curl) {
- CURLcode res;
- curl_easy_setopt(curl, CURLOPT_URL, "http://example.com");
- res = curl_easy_perform(curl);
- curl_easy_cleanup(curl);
- }
- .fi
