curl::shareinit

This procedure must be the first one to call, it returns a shareHandle that you need to use to share data among handles using the -share option to the configure command. The init MUST have a corresponding call to cleanup when the operation is completed.

RETURN VALUE

shareHandle to use.

The parameter specifies a type of data that should be shared. This may be set to one of the values described below:

cookies: Cookie data will be shared across the easy handles using this shared object.
