uninstantiation_error/1

Description

uninstantiation_error(Culprit)

Throws an uninstantiation error. Used when an argument or one of its sub-arguments is bound but a variable is required. For example, trying to open a file with a stream argument bound.

This built-in method is declared private and thus cannot be used as a message to an object. Calling this predicate is equivalent to the following sequence of calls:

...,
context(Context),
throw(error(uninstantiation_error(Culprit), Context)).

This allows the user to generate errors in the same format used by the runtime.
