CURL.Release

End a CURL session.

Component Version macOS Windows Server FileMaker Cloud FileMaker iOS SDK
CURL 2.5 Yes Yes Yes Yes Yes
MBS( "CURL.Release"; curl )   More

(old name: CURL.Cleanup)

Parameters

Parameter Description Example value
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 )
