ad_unless_script_abort (public)

 ad_unless_script_abort body non_abort_action

Defined in packages/acs-tcl/tcl/exception-procs.tcl

Execute the provided body in the callers' environment. When the body does not raise an "ad_script_abort" exception, the "non_abort_action" is also executed. This pattern is useful when handling client requests and where the "non_abort_action" is used to return results to the client. When "ad_script_abort" is executed, the connection is usually closed, and any attempt to talk to the client over the closed connection will fail. The handling of script_abort exceptions is done usually in the request processor. The function is useful when registering own request procs (e.g., via "ns_register_proc") where the OpenACS request processor is not involved.

Parameters:

body - script, which is always executed
non_abort_action - script, which is executed unless the body was aborted.
