#pragma omp ordered Preprocessing Directive (C Only)

The omp ordered directive identifies a structured block of code that must be executed in sequential order.

Syntax

#pragma omp ordered
    statement_block

Notes
The omp ordered directive must be used as follows:

It must appear within the extent of a omp for or omp parallel for construct containing an ordered clause.
It applies to the statement block immediately following it. Statements in that block are executed in the same order in which iterations are executed in a sequential loop.
An iteration of a loop must not execute the same omp ordered directive more than once.
An iteration of a loop must not execute more than one distinct omp ordered directive.
