(old name: CURL.Cleanup)
Parameters
| Parameter | Description | Example |
|---|---|---|
| curl | The CURL session handle. | $curl |
Result
Returns "OK" on success or error on failure.
Description
End a CURL session.This function must be the last function to call for a CURL session. It is the opposite of the CURL.New function and must be called with the same handle as input that the CURL.New call returned.
This will effectively close all connections this handle has used and possibly has kept open until now. Don't call this function if you intend to transfer more files.
Any uses of the handle after this function has been called and have returned, are illegal. This kills the handle and all memory associated with it!
Please don't try to close a running transfer.
Used to be named CURL.Cleanup, but we changed named to CURL.Release in version 10.2.
Examples
Cleanup session:
# for every New call
$curl = MBS( "CURL.New")
# work with $curl
# you need a release call on the end
MBS( "CURL.Release"; $curl )

Set Variable [$curl; Value:MBS("CURL.New")]
#this is URL to download
Set Variable [$url; Value:"https://www.monkeybreadsoftware.com/filemaker/test.txt"]

Set Variable [$name; Value:MBS( "Path.LastPathComponent"; $URL )]
#now make temp file path
Set Variable [$path; Value:MBS( "Path.AddPathComponent"; MBS( "Folders.SystemTemporary" ); $name )]
#set URL to download
Set Variable [$r; Value:MBS("CURL.SetOptionURL"; $curl; $url)]
#open destination file
Set Variable [$r; Value:MBS("CURL.CreateOutputFile"; $curl; $path)]
#run transfer
