.SH DESCRIPTION
|
2002-03-04 21:06:46 +08:00
|
|
|
This function must be the first function to call, and it returns a CURL easy
|
2014-10-21 16:26:40 +08:00
|
|
|
handle that you must use as input to other functions in the easy
|
|
|
|
|
interface. This call \fBMUST\fP have a corresponding call to
|
2004-02-27 23:34:06 +08:00
|
|
|
\fIcurl_easy_cleanup(3)\fP when the operation is complete.
|
2002-03-04 18:09:48 +08:00
|
|
|
|
2014-10-21 16:26:40 +08:00
|
|
|
If you did not already call \fIcurl_global_init(3)\fP, \fIcurl_easy_init(3)\fP
|
2021-11-26 15:46:59 +08:00
|
|
|
does it automatically. This may be lethal in multi-threaded cases, since
|
2014-10-21 16:26:40 +08:00
|
|
|
\fIcurl_global_init(3)\fP is not thread-safe, and it may result in resource
|
|
|
|
|
problems because there is no corresponding cleanup.
|

|
|
|
|
2020-12-31 17:11:49 +08:00
|
|
|
You are strongly advised to not allow this automatic behavior, by calling
|
2021-11-26 15:46:59 +08:00
|
|
|
\fIcurl_global_init(3)\fP yourself properly. See the description in
|

|

this function.
