Directives

Semantics

The default clause determines the implicit data-sharing attribute of certain variables that are referenced in the construct, in accordance with the rules given in Section 5.1.1.

If data-sharing-attribute is not none, the data-sharing attribute of all variables referenced in the construct that have implicitly determined data-sharing attributes will be data-sharing-attribute. If data-sharing-attribute is none, the data-sharing attribute is not implicitly determined.

Restrictions

Restrictions to the default clause are as follows:

If data-sharing-attribute is none, each variable that is referenced in the construct and does not have a predetermined data-sharing attribute must have its data-sharing attribute explicitly determined by being listed in a data-sharing attribute clause.

∙ If data-sharing-attribute is firstprivate or private, each variable with static storage duration that is declared in a namespace or global scope, is referenced in the construct, and does not have a predetermined data-sharing attribute must have its data-sharing attribute explicitly determined by being listed in a data-sharing attribute clause.
