curl_easy_init(3) Library Functions Manual curl_easy_init(3)
NAME
curl_easy_init - create an easy handle
SYNOPSIS
#include <curl/curl.h>
CURL *curl_easy_init();
DESCRIPTION
This function allocates and returns a CURL easy handle. Such a handle
is used 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.
The easy handle is used to hold and control a single network transfer.
It is encouraged to reuse easy handles for repeated transfers.
An alternative way to get a new easy handle is to duplicate an already
existing one with curl_easy_duphandle(3), which has the upside that it
gets all the options that were set in the source handle set in the new
copy as well.
If you did not already call curl_global_init(3) before calling this
function, curl_easy_init(3) does it automatically. This can be lethal
in multi-threaded cases for platforms where curl_global_init(3) is not
thread-safe, and it may then result in resource problems because there
is no corresponding cleanup.
You are strongly advised to not allow this automatic behavior, 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.
