Synopsis

Description

This function is used to examine the current ADP exception state.

ns_adp_exception ?state?

The function returns 0 if the exception state is ok and 1 otherwise.

If the optional state argument is passed, a variable with that name will be set for the caller, and will contain the exception state with one of the following possible values:

  • ok: ADP was evaluated successfully

  • overflow: Stack overflow occurred. This might happen, for example, if there was a recursive call to ns_adp_include.

  • abort: An attempt to debug failed or ns_adp_abort was called.

  • break: ns_adp_break was called

  • unknown: Unrecognized exception status. This should not occur.
