Detailed Description

Helper functions for OpenMP.

This file contains wrapper functions for standard OMP functions, that work with and without OMP support. This saves the use of #ifdef statements around omp functions in the ARTS main code.

All functions start with arts_omp. Otherwise, names are the same as the standard OMP function names.
