NAME
curl_easy_init - Start a libcurl easy session SYNOPSIS
#include <curl/curl.h> CURL *curl_easy_init( ); DESCRIPTION
This function must be the first function to call, and it returns a CURL easy handle that you must use as input to other functions in the easy interface. This call MUST have a corresponding call to curl_easy_cleanup(3) when the operation is complete. If you did not already call curl_global_init(3), curl_easy_init(3) does it automatically. This may be lethal in multi-threaded cases, since curl_global_init(3) is not thread-safe, and it may result in resource problems because there is no corresponding cleanup. You are strongly advised to not allow this automatic behaviour, by calling curl_global_init(3) yourself properly. See the description in libcurl(3) of global environment requirements for details of how to use this function. RETURN VALUE
If this function returns NULL, something went wrong and you cannot use the other curl functions. EXAMPLE
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); } SEE ALSO
curl_easy_cleanup(3), curl_global_init(3), curl_easy_reset(3), curl_easy_perform(3) libcurl 7.54.0 February 03, 2016 curl_easy_init(3)

NAME
curl_easy_cleanup - End a libcurl easy handle SYNOPSIS
#include <curl/curl.h> void curl_easy_cleanup(CURL *handle); DESCRIPTION
This function must be the last function to call for an easy session. It is the opposite of the curl_easy_init(3) function and must be called with the same handle as input that a curl_easy_init(3) 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 curl_easy_cleanup(3) (if previously set for the han- dle using curl_easy_setopt(3)). Like if libcurl decides to shut down the connection and the protocol is of a kind that requires a com- mand/response sequence before disconnect. Examples of such protocols are FTP, POP3 and IMAP. Any use of the handle after this function has been called and have returned, is illegal. curl_easy_cleanup(3) kills the handle and all mem- ory associated with it! 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. RETURN VALUE
None EXAMPLE
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); } SEE ALSO
