! 25: .SH NAME
! 26: curl_easy_cleanup - End a libcurl easy handle
! 27: .SH SYNOPSIS
! 28: .B #include <curl/curl.h>
! 29:
! 30: .BI "void curl_easy_cleanup(CURL *" handle ");"
! 31: .SH DESCRIPTION
! 32: This function must be the last function to call for an easy session. It is the
! 33: opposite of the \fIcurl_easy_init(3)\fP function and must be called with the
! 34: same \fIhandle\fP as input that a \fIcurl_easy_init(3)\fP call returned.
! 35:
! 36: This might close all connections this handle has used and possibly has kept
! 37: open until now - unless it was attached to a multi handle while doing the
! 38: transfers. Don't call this function if you intend to transfer more files,
! 39: re-using handles is a key to good performance with libcurl.
! 40:
! 41: Occasionally you may get your progress callback or header callback called from
! 42: within \fIcurl_easy_cleanup(3)\fP (if previously set for the handle using
! 43: \fIcurl_easy_setopt(3)\fP). Like if libcurl decides to shut down the
! 44: connection and the protocol is of a kind that requires a command/response
! 45: sequence before disconnect. Examples of such protocols are FTP, POP3 and IMAP.
! 46:
! 47: Any use of the \fBhandle\fP after this function has been called and have
! 48: returned, is illegal. \fIcurl_easy_cleanup(3)\fP kills the handle and all
! 49: memory associated with it!
! 50:
! 51: Passing in a NULL pointer in \fIhandle\fP will make this function return
! 52: immediately with no action.
! 53: .SH "OLD TIMES"
! 54: For libcurl versions before 7.17,: after you've called this function, you can
! 55: safely remove all the strings you've previously told libcurl to use, as it
! 56: won't use them anymore now.
! 57: .SH RETURN VALUE
! 58: None
! 59: .SH EXAMPLE
! 60: .nf
! 61: CURL *curl = curl_easy_init();
! 62: if(curl) {
! 63: CURLcode res;
! 64: curl_easy_setopt(curl, CURLOPT_URL, "http://example.com");
! 65: res = curl_easy_perform(curl);
! 66: curl_easy_cleanup(curl);
