.SH DESCRIPTION
The \fItype\fP parameter specifies what specific data that should no longer be
shared and kept in the share object that was created with
\fIcurl_share_init(3)\fP. In other words, stop sharing that data in this
shared object. The given \fItype\fP must be one of the values described
below. You can set \fICURLSHOPT_UNSHARE(3)\fP multiple times with different
data arguments to remove multiple types from the shared object. Add data to
share again with \fICURLSHOPT_SHARE(3)\fP.
