 === Shared variables ===
 
 * `$omp_gshared $omp_gshared_create($omp_gteam, void *original)`
+ * creates new global shared object, associated to the given global team.  A pointer to the shared variable that this object corresponds to is given.  The new object is initialized by copying the values from the original variable.
