4 Base Language Formats and Restrictions

This section deﬁnes concepts and restrictions on base language code used in OpenMP. The concepts help support base language neutrality for OpenMP directives and their associated semantics.

Restrictions

The following restrictions apply generally for base language code in an OpenMP program:

Programs must not declare names that begin with the omp_ or ompx_ preﬁx, as these are reserved for the OpenMP implementation.

∙ Programs must not declare a namespace with the omp or ompx names, as these are reserved for the OpenMP implementation.
